The perfect rainbow veggie slice to have in the fridge for a nutritious grab-n-go breakfast, or to pack in the little one's lunch box to keep them fuelled for the day. Loaded with veggies, let the kids get involved and pick their fav veggies to include - maybe making it more appetizing for them...who knows with kids? This vegetable slice is also a great way to clean out the fridge at the end of the week, using whatever vegetables you have left hanging out in the crisper.
Super versatile, kid-friendly, and make-ahead friendly. A great addition to your meal planning recipe collection.

Easy Broccoli and Cheddar Rainbow Veggie Slice
This is a great recipe for using up a lot of veggies leftover in the crisper at the end of the week.
I always have some leftover broccoli, so for this version, I used broccoli florets and stems, red cabbage, grated carrot, corn kernels, cheese, and spring onions.
The best thing about this veggie slice though is that it is super versatile, and lends itself well to a variety of vegetables. So if you don't have the specific listed ingredients in your fridge then feel free to try adding some of these instead:
- leftover broccoli rice in place of the florets
- thinly sliced kale or baby spinach
- shelled peas: fresh or frozen peas will do
- shelled edamame
- red onion
- chopped green beans
- chopped mushrooms
- chopped cooked pumpkin or sweet potato
- chopped cherry tomatoes
- diced red capsicum (bell pepper)
- grated and drained zucchini.
The sky is the limit. Although if you are using something like zucchini, which tends to have excess moisture, then be sure to get as much liquid out as possible before adding to the rest of the mixture.
Although you will need cheese!
Again though, a mixture of whatever cheese you have on hand should work well (within reason of course). We always tend to have cheddar cheese or feta cheese on hand, and they are always a great option.
We have been known to add some leftover bacon as well, which is always popular with the husband.
TIP: Use a food processor to quickly chop the vegetables into even-sized pieces.
Assembly Instructions
Once your veggies are prepped and chopped it is pretty much as easy as adding all of the ingredients to a large bowl and giving everything a good stir until well combined and the egg is coating the other ingredients.
Once everything is combined, pour mixture into a baking dish that has been lightly brushed with olive oil and pop it into the oven.
It should be deliciously golden brown on top when ready.
Allow to cool slightly and then use a sharp knife to cut into squares.
Too easy.
Tips For Getting The Kids Involved
This healthy snack is so easy even kids can put it together once the veggies are chopped and ready to go.
If your kids aren't huge veggie fans then start slowly with some vegetables they do like, and maybe add some cooked and chopped bacon into the mix as well to make it more appetizing for them.
Personally, my kids love seeing how many different colors they can fit into the egg bake, so I let them go wild with their imaginations and add in whatever makes them happy. Just make sure you have enough egg mixture to cover all of the veggies.
The only caveat is that if they make it, they have to eat it!
No food wasters in this house.
I use this casserole dish, it's so beautiful it can make even a simple veggie slice like this look fancy:
A rainbow veggie slice is great for:
- a quick and easy grab-n-go breakfast;
- when you are cooking breakfast or lunch for a crowd and want to keep it simple but delicious;
- lunchboxes, just add an ice pack to the lunchbox to keep it cool and prevent it from getting soggy;
- a nice brunch;
- a picnic;
- and easy dinner when paired with a nice side salad;
- meal prepping for the week ahead, just keep stored in an airtight container in the fridge and pull it out as needed.
Can This Veggie Slice Be Prepped In Advance?
Yes, it certainly can.
Simply make it up as per the instructions, and store it in the fridge in a glass container with a lid, or another fridge-friendly container.
To reheat, simply pop a slice into the microwave for around a minute, or alternatively, into the air fryer.
It can also be enjoyed cold, and my kids regularly enjoy it cold as part of their lunch. I do include an ice-pack to stop it from getting soggy though.
