In a medium-sized bowl, beat eggs until light and lemon colored.
Add flour, baking powder, salt, cottage cheese, jack cheese and butter; beating until smooth. Stir in chiles.
Pour mixture into a well-buttered 9 x 13 inch baking dish. Bake in preheated oven for about 35 minutes or until top is browned and center appears firm. This recipe could be easily halved and baked in individual ramekins(or custard dishes )for a little less time.
