Potato Pizza

5 C. peeled & thinly sliced potatoes (I used my slicing blade on my food processor for this)
Pepper
1 1/2 lbs. hamburger
1/2 small onion chopped
1 can (10 3/4 oz) Cheddar Cheese Soup
1 C. milk
4 oz melted cheddar cheese (OK, so in reality I use 2 full cups....there is no such thing as too much cheese)
1 can (10 3/4 oz) tomato soup
1 C. shredded mozzarella cheese.

Grease 9x13 glass Pyrex dish. Lay potatoes out flat in pan in layers. Sprinkle generously with pepper. Brown ground beef and onion. Drain. Stir cheese soup, milk, and melted cheddar cheese together until smooth (works best if cheese and soup are warm.  In fact, I do this in a sauce pan over heat as I melt the cheddar cheese). Mix ground beef and cheese mix, spread over potatoes. Bake @ 350 for 1 hour or until potatoes are done.

Top with tomato soup and mozzarella cheese. Bake 5 more minutes or until cheese is melted.
