Breakfast tater tot casserole

1 pound ground pork breakfast sausage cooked (or cubed ham or bacon, whatever you like best as long as it is cooked)
2-4 cups shredded cheddar cheese
2 cups milk
4 eggs
2 pounds frozen tater tots

Preheat oven to 350 degrees. Spread the sausage, bacon or ham evenly in the bottom of a 9-by-13 pan. Spread cheese over meat. I use 4 cups of cheese, but you can use less if you prefer to reduce the calories. In large bowl, beat together milk and eggs. Pour over cheese (may be refrigerated overnight at this point). Top with frozen tater tots. Bake in preheated oven for 45 minutes. Some ovens may take more or less time. Cool for 5 to 10 minutes before serving.
