Layer half the frozen potatoes, half the bacon or sausage, and 1 cup shredded cheese in your greased crock pot and sprinkle on salt and pepper. Repeat these layers one more time.
Sprinkle the remaining 1 cup shredded cheese over the top evenly.
Beat the eggs and milk together. Pour the egg mixture over the cheese evenly in the crockpot.
Cook on low for 7 to 8 hours (or HIGH for 3-4 hours) or until eggs are set and thoroughly cooked.
