I love frittatas. You can put anything in them. You can add leftover veggies, meats, cheeses; you can add any flavor combination you like. I added sliced onions and mushrooms and softened them up a bit. Then I added some sliced ham to warm it through. Then I added them to 6 whisked eggs and poured them back in the pan. Finally, I added sliced kalimata olives and goat cheese to the top. I cooked it on the stove top for a few minutes until the bottom is set. Then I put it in the oven on broil until the top was done, about 3 minutes. This was a great combination!
