Brown sausage and drain. In a very large bowl, combine sausage, hash browns (do not have to be thawed), the Mexican cheese and half of the cheddar cheese. Beat eggs, milk and seasonings for about a minute with a hand mixer, then combine with the sausage and egg mixture. Pour into a greased 9x13 glass baking dish, top with remaining cheddar cheese, sprinkle with paprika, cover and refrigerate overnight. Remove from refrigerator about 2 hours before serving to come to room temperature. Bake for 55-60 minutes at 350 degrees. Let stand 10 minutes. Serve with salsa.
Enjoy!!!
