What is a Frittata Quiche? Basically a frittata with flour and baking powder in it. Why? This makes it more filling and slices into tidy little portable wedges. And this month is all about easy recipes to feed the family, or yourself. With whole wheat flour, veggies and protein all in one dish, this frittata quiche ticks all the boxes when it comes to meal time. If you have leftovers that need to be used up, the meat, cheese and vegetables can easily be swapped out for what you have on hand. And yes, you can use gluten free flour if you want to.
