1/4 teaspoon white pepper
1  whole egg, lightly beaten
2  egg whites, beaten softly-stiff

Preheat oven to 350 degrees. Mix the cooked noodles with the 3 cheeses, sour cream, Worcestershire, and salt and pepper. Mix in the whole-beaten egg and then gently fold in the egg whites. Pour the mixture into a non-stick sprayed baking dish. Dust top with a sprinkling of paprika.

Bake 35 to 45 minutes, until center is set and edges are golden brown. Remove from oven and let set 5 minutes before serving. Garnish each serving with additional sour cream.
