Cleaning out the frig today and that means taking a look at all those stray vegetables, chunks of cheese, and last pieces of meat and putting them to good use. A frittata is a perfect dish for using up those stragglers and when done correctly can be a thing of beauty. An Italian dish, similar to an omelette or quiche, it can be served any time of the day. I like to serve it for Sunday brunch. This recipe is going to use up some of the leftover mushrooms, spinach, and tomatoes I have accumulated during this meatless month.
