This is a great recipe (slightly altered) from http://www.incredibleegg.org/.
You can size it up or down, and personalize the ingredients however you'd like. The recipe calls for 1 cup of "filling", which can be any combination of cooked meat, seafood or poultry, cheese, vegetables and/or cooked pasta or grains. Chop the filling into fairly small and make sure it's well-drained.
To make fewer or more servings: Adjust the amounts of filling, liquid, seasonings and the pan size proportionally to the number of eggs used. For 2 eggs, use a 6-inch pan; for 6 eggs, use an 8- or 10-inch pan; for 8 eggs, use a 10- to 12-inch pan.
