It can be a challenge to find grab-and-go breakfast options that are healthy. But with just a little bit of planning, these muffin tin frittatas make it easy! Apart from the base ingredients, you can add whatever toppings you enjoy—including some leftover vegetables that might otherwise go to waste.

This breakfast or snack cake is perfect for adjusting the ingredients to whatever you like or whatever you have on hand. Have too much zucchini? Use it in place of the apples or carrots. Don’t like coconut? Omit it and use some dried fruit instead. The possibilities are endless!
