This was JUST the type recipe that I was looking for, for brunch. My friend did NOT have a cast-iron skillet, which is what I normally make frittatas in, so being able to make the entire thing in a Pyrex pie pan was crucial. We didn't want to add the meat so we made this following the recipe except the ham. It turned out so good and so flavourful that there were no leftovers! I'm so glad that you posted this basic and easy recipe. Thanks!

This was my first attempt at a frittata. I thought it would be difficult, but it was so easy. I did have to make a couple of changes because I had to use what I had on hand. I used Pepper Jack cheese instead of Feta and instead of 1 cup chopped onion, I used about 1/2 cup chopped fresh green onions. I would recommend this to anyone. What a great dish for those cold winter nights!!!!

I used an entire box of frozen spinach, opted for mushrooms and passed on the ham. Served it with fresh fruit and toast. Everyone was pleased. Update: used 1 cup smoked ham, 3/4 cup mushrooms, 1 cup feta, 3/4 cup moz, 9 eggs and whole box frozen spinach. Wonderful again!
