I was pretty disappointed. I really think frittata's do best in the oven. My green peppers seemed to move towards the middle of the pie plate as it cooked. The edges were done much faster than the middle, so I had to leave it cooking longer than the recipe called for. Then the edges were way overdone, chewy, & dry. I had to cut the edges off and put the plate back in to finish cooking the middle. I won't attempt a microwave version again.
