New Year's Breakfast Casserole

This casserole is our family's New Year's Day tradition and so good. But how could it not be good with all that butter and cheese . . .

10 eggs
1/2 c flour
1 tsp baking powder
1/2 tsp salt
1/2 c melted butter
1 pint cottage cheese
1 lb shredded jack cheese
1 lb shredded cheddar cheese
2 small cans chilis (optional)

Mix all together and pour into 9 x 13 pan. Bake at 350* for about 40 minutes. Serve with sour cream and salsa. (I'm thinking I'll serve it with Jennifer's salsa below. It sounds so yummy!)
