My mom would often make this Christmas morning (minus the sausage), along with cinnamon rolls.
1/2 cup melted butter
1/2 cup flour
1 tsp baking powder
1 lb. Monterey Jack cheese, shredded
2 cups cottage cheese
1 can diced green chilis
browned sausage, optional
Beat eggs. Add all other ingredients. Pour into a 9x13 baking dish. Bake at 400 for 15 minutes, then reduce heat to 350 for 35-40 minutes.
