For a good frittata:

4 eggs
3 ounces cream cheese
1/4 cup cream
1/4 cup parmesian cheese
salt and pepper to taste
green onions, chopped (optional) You can use mushrooms or whatever you would like as a filler.

Blend all ingredients together. Melt butter in a ovenproof pan and cook as you would scrambled eggs, but just until they are still a little runny. Place pan under preheated broiler until golden brown, this only takes a minute or two.

Enjoy!
