In a large mixing bowl, beat eggs on medium-high speed for 3 minutes or until light and lemon-colored. Combine the flour, baking powder and salt; gradually add to eggs. Stir in the cheeses and chilies.

Pour into a greased 13-in. x 9-in. x 2-in. baking dish. Bake, uncovered, at 350° for 35-40 minutes or until a knife inserted near the center comes out clean. Let stand for 5 minutes before serving. Serves 12.
