Rainbow Lunchbox Ideas: 5 Easy Colourful School Lunches

Five days. Five colourful lunch ideas. Plenty of easy ways to add a little more variety to the week — without turning school lunch into a project.

A red lunch on Monday. Sunshine yellow on Tuesday. Green on Wednesday... Eating the rainbow sounds like one of those ideas that could quickly become another job on the school-week list. But it really doesn't need to.

Rather than trying to squeeze every colour into every lunchbox, we're spreading the rainbow across the week. Each day has a loose colour theme built around familiar, easy-to-pack foods, before bringing the whole rainbow together on Friday.

Before we start, let's stay realistic: there should be no expectation that everything will be eaten. And if you know that your kids hate one of our suggested foods, there's no need to follow these lunchboxes exactly. Think of them as inspiration and a little fun to bring more colour and variety into the usual lunchbox rotation.

Why eat a variety of colours?

Different fruits, vegetables, legumes, wholegrains and other plant foods bring different combinations of nutrients and fibre to the diet, which is one reason Australian dietary guidance encourages eating a wide variety of nutritious foods — including different types and colours of vegetables.

That doesn't mean a lunch needs to contain every colour of the rainbow to be a good lunch. A child who happily eats some sort of variety doesn't suddenly need purple cabbage added for good measure. But why not introduce new foods in a playful way to see what could be added to the repertoire?

GOOD TO KNOW: What does “30 plants a week” actually mean?
You may have heard the recommendation to aim for 30 different plant foods each week. It comes largely from the American Gut Project, a large citizen-science microbiome study that found differences in the gut microbiomes of people who reported eating more than 30 different types of plants per week compared with those eating 10 or fewer.
It does not mean children have an official requirement to eat 30 plants every week, and 30 isn't a magic nutritional target. The more useful takeaway is simply variety.
And “plants” means much more than fruit and vegetables. Wholegrains, beans, lentils, chickpeas, seeds, herbs and spices can all add to the mix too. It can be quite good fun to count all the plants in your meals, and some kids will feel encouraged to try something with an extra two or more spices, just to get ahead on the family leaderboard.

Monday: Red + Pink

(packed in the Stainless Steel Bento 5 Lunchbox V2)

We're starting the week with perhaps the easiest colour of them all: red! Strawberries, watermelon, tomatoes and red capsicum make this one naturally bright, while mini pizza scrolls keep the main part of lunch familiar and filling.

Pack:

Mini pizza scrolls

Spread a wholemeal wrap or sheet of puff pastry with tomato passata, sprinkle with cheese, ham if you like and dried oregano, roll, slice, and bake until golden.

Add:

• strawberries

• watermelon cubes

• cherry tomatoes

• red capsicum strips

• hummus for dipping

The Bento 5 Lunchbox V2 makes it easy to keep the fresh foods separate from the pizza scrolls, with the smaller silicone section handy for hummus or another favourite dip.

Mix it up

Not a tomato or capsicum child? Skip it.

Try:

• raspberries

• red grapes

• red apple with the skin on

• plum

• another serving of strawberries

• a familiar cracker or cheese instead

The colour theme is there to make lunch fun. It isn't a checklist.

GOOD TO KNOW: A few ingredients can add a surprising amount of plant variety
. A lunch like this could contain around 10 different plants: whole wheat, seeds, tomato, capsicum, strawberries, watermelon and chickpeas in the hummus, plus spices — without looking remotely like a “30 plants” challenge.

Tuesday: Sunshine Orange + Yellow

Packed in the Bento 2 Lunchbox + Insulated Food Jar

A warm lunch changes things up today, with the Food Jar holding a simple pumpkin and sweet potato soup, while the Bento 2 Lunchbox carries the crunchy, dippable extras.

Easy Pumpkin + Sweet Potato Soup

You don't need a separate child-specific soup recipe for this one. Make a batch for dinner and use the leftovers for lunch.

You'll need:

• pumpkin

• sweet potato

• onion

• red lentils

• low-salt stock

• a little olive oil

• optional milk, cream or coconut milk to finish

Cook until everything is soft, then blend until smooth.

Preheat the Food Jar according to its care instructions before adding hot soup in the morning.

Pack alongside it:

• wholegrain cheese toast fingers for dipping

• carrot sticks

• mandarin segments

• yellow capsicum

• corn or mango, depending on what you have

The Bento 2 Lunchbox works particularly well here because the soup does the heavy lifting and the Bento simply carries a couple of sides.

Mix it up

Skip anything your child doesn't eat.

You could use:

• pineapple

• rockmelon

• orange

• roasted sweet potato pieces

• corn crackers

• cheese cubes

• a favourite bread roll

GOOD TO KNOW: “Eating more plants” doesn't mean serving more raw vegetables.
Plants can turn up as soup, pasta sauce, hummus, wholegrain bread, baked snacks and dinner leftovers just as easily as they can appear as veggie sticks.
If a child isn't interested in a box full of raw vegetables, you are far from out of options

Wednesday: Green Day

Packed in the Stainless Steel Bento 5 Lunchbox V2

Green gets a reputation for being the difficult colour. So we're giving it a head start with pasta.

Easy Green Pesto Pasta

Blend together:

• basil

• baby spinach

• cooked peas

• parmesan

• olive oil

• a squeeze of lemon and maybe some crushed garlic

Toss through your child's preferred pasta and chill.

No need to hide the ingredients or call it something other than what it is. If spinach isn't welcome, make a regular basil pesto. If pesto itself isn't happening, use their usual pasta and let the green sides do the colouring.

Add:

• green grapes

• kiwi fruit

• cucumber

• sugar snap peas or edamame

• yoghurt or a favourite dip

Mix it up

Your version might simply be:

their normal sandwich + green grapes + cucumber.

That still counts as joining in.

GOOD TO KNOW: Familiar foods belong in the lunchbox too.
Variety doesn't mean replacing everything a child already likes.
In fact, familiar foods can give children something reliable to eat while different foods are offered alongside them. Lunch does not need to become food-exposure homework.

Thursday: Blue + Purple

Packed in the Classic Bento 3 + Snack Pot Duo

There simply aren't as many naturally blue foods, so we're letting purple help out. And that's fine. The rainbow police aren't coming.

Pack:

Chicken + purple slaw wrap

Fill a wrap with:

• cooked chicken

• cheese or avocado, if liked

• a small amount of finely shredded purple cabbage

• yoghurt-based dressing or another familiar spread

In the Bento:

• chicken and purple slaw wrap

• blueberries

• purple grapes

Snack Pot Duo:

Pot 1: Purple Carrot Sticks (or just crackers ;-))
If you can find them, and if they eat carrots. Otherwise, let's not reinvent the wheel.

Pot 2: Beetroot hummus
Blend chickpeas, cooked beetroot, tahini, lemon and olive oil until smooth. Or just buy ready-made from the shops.

If beetroot hummus is likely to go to waste, use a familiar dip instead. No points are awarded for returning home with an untouched purple snack. Unless they wanted to try it, of course.

GOOD TO KNOW: Purple isn't compulsory.
“Eat the rainbow” is a handy reminder to vary the foods we eat, but there is no requirement to tick off a specific colour chart each day.
Brown and white plant foods count too. Think oats, wholegrains, chickpeas, cauliflower, mushrooms, pears, bananas, onions and potatoes.
Colour is a prompt for variety — not the nutritional goal itself.

Friday: The Full Rainbow

Packed in the Stainless Steel Bento 5 Lunchbox V2

Friday brings the whole week together. And deliberately, this is the easiest box of them all.

Start with a main food your child already enjoys. That could be:

• a sandwich

• wrap

• leftover slice

• crackers and cheese

• savoury muffin

• scroll

Then use the remaining Bento compartments to create the rainbow.

One easy combination:

Red: strawberries
Orange: carrot
Yellow: corn or yellow capsicum
Green: cucumber or green grapes
Blue/Purple: blueberries or purple grapes

Add hummus, yoghurt or a favourite dip to one of the smaller sections if it works with the lunch. That's it. No rainbow-shaped sandwich expected.

GOOD TO KNOW:
The easiest rainbow lunch starts with the lunch you already make.
You don't need to redesign the whole lunchbox. Keep the sandwich, wrap or crackers your child knows, then look in the fridge and see whether one or two different colours could be added around it. Maybe even share the idea with your child and go shopping together. You'll be surprised how much some kids are willing to give a go if it is tied to a game.
Changing the fruit from apple to kiwi one week is variety. Adding corn to a quesadilla is variety. Using a wholegrain wrap instead of the usual bread occasionally is variety too.

Your Rainbow Lunchbox Cheat Sheet

You don't need our exact combinations. Use whatever is in season, affordable and — most importantly — likely to be eaten.

And remember that plant variety can also come from less obvious places:

• wholemeal bread

• oats

• pasta

• rice

• lentils

• beans

• chickpeas

• seeds

• herbs

• spices

You don't need 30 individual fruit and vegetable compartments to add variety to the week.

But what if my child is a fussy eater?

Keep the rainbow idea very loose. If your child currently eats only a small number of fruits or vegetables, this is not a reason to replace their reliable lunch with five unfamiliar foods. Use what they already eat. If red means strawberries three times this week, excellent. If the green lunch contains green grapes but absolutely no broccoli, also excellent.

Children's tastes, appetites and willingness to try foods vary enormously. A lunchbox also has a fairly important practical job: giving your child something they are comfortable eating during a busy school day.

So think add and rotate, rather than remove and replace.

You might:

• swap one familiar fruit for another

• serve a favourite dip beside a different vegetable

• change the grain in a muffin or wrap

• add lentils to a soup (and puree it)

• use leftover vegetables inside a pasta sauce

• sprinkle seeds into a familiar homemade snack where appropriate

• let your child choose the colour for tomorrow

Small changes still create variety over time.

Does a healthy lunchbox need to look like this?

Absolutely not. A beautifully organised rainbow Bento makes a great photo. That doesn't mean every Wednesday morning needs to look like one. Some days lunch will be leftovers. Some days it will be a sandwich, apple and yoghurt. Some days you'll use the last things left in the fridge and be quietly pleased there was food in the lunchbox at all.

Australian healthy-eating guidance encourages variety across the five food groups, and Children's Health Queensland makes another point we think is equally worth remembering: lunchboxes don't need to be fancy.

If you find nutritious foods your child enjoys, keep packing them. The rainbow is simply a fun way to shake up the rotation when you feel like it.

The Takeaway

Eating a wider variety of plant foods can sound complicated, but in a real family kitchen, it can be much simpler. Different fruit in the shopping basket. A handful of lentils in the soup. Wholegrain seeded bread. Chickpeas blended into hummus. A few vegetables across dinner and lunch. Herbs in a sauce. They all add up.

So don't worry about building the perfect rainbow lunchbox. Have some fun with colour, keep the foods your child already loves, and see where a little extra variety can fit.
