A frittata (also known as crustless quiche) is a perfect palette for colorful vegetables and strongly flavored cheeses. What I love about frittatas is that they are one of the few egg dishes that are delicious at room temperature and can be stored in the refrigerator (or even frozen) for days. This one is not just for breakfast - Try it for lunch or dinner with a salad or steamed veggies. Eat hot or at room temperature - Leftovers can be heated in toaster oven or microwave. I designed this recipe to be gluten-free, using my homemade fresh gluten-free Italian breadcrumbs - But you can use any type of breadcrumbs you like.
