Well, it's a little hard to say, because you could add any ingredients under the sun to these. But basically, I allowed about 1/2 egg per cup. "Saute" the onions by adding a bit of butter to frozen onions/peppers microwaving for 2 minutes. Spray muffin tin cups with non-stick cooking spray and line each with a slice of ham. Add the cooked onions/peppers, then sprinkle in some shredded cheese. Pour in the egg mixture (eggs, cream, salt and pepper) and beat well with a fork. Chop a small green onion top and divide onto each. Bake at 350 degrees for 20 - 25 minutes.
