It was easy enough and looked pretty, but... somehow apples and eggs just don't mix that well for me.
For those who found it bland, you can add spices... Rosemary, Thyme, Sage, Peppers, Chilis...
I loved this recipe! I used Beecher's cheese (Jack) instead of cheddar, and added some red onion and bacon as suggested by previous reviewers. I also used some of the bacon grease and about half a tablespoon or less of the butter on the bottom of the skillet to add additional flavor. My family was quite impressed when I brought this frittata to the table. The circular design of the apples on top looks fancy!
