Kids Recipe Challenge winning recipe: 3rd Place!

Sophie, in Kitchener, loves this nutritious and colourful lunch.

Instead of buying packaged convenience food containers, make your own! Pack the different parts of this “sandwich” for lunch at school. It’s a little messy because you don’t need any utensils - but that’s why kids would love making this recipe.
