Tator Tot Casserole

I thought the regular versions where boring so I modified the recipe as follows.

1 bag of tator tots
1 lb ground beef
1 small onion
1 can cream of chicken or mushroom soup
1 cup sour cream
2 cups milk
1 cup cheddar or mozzarella cheese
1 tbs garlic powder
2 tsp salt
1 tsp pepper

Preheat oven to 375. Cook the ground beef and onion in a pan on the stove. Then mix together the remaining ingredients in a bowl. Place just enough tator tots in the bottom of a 9x13 casserole dish to cover it. Then pour the meat mixture over the tator tots and the rest over the top of that. Cover the top of it in cheddar or mozzarella cheese and bake in over for 40-60 minutes. Enjoy!
