Meat and potato casserole (a real man's dish!)

I made this dish I call a meat and potato casserole last night. It wasn't all that beautiful to look at but man is it delicious. I browned some ground beef, boiled some sliced/diced/cubed potatoes, stirred in a can of cream of mushroom soup, a little sour cream, and some of the potato broth, put it all in a casserole dish, topped with Parmesan cheese and baked briefly. It would have looked better if I'd added some vegetables and topped with yellow cheese, but I was using what I had available.

Well, that's pretty much the directions but here it is more precisely:

Beef and Potato Casserole

1 lb. ground beef
7-8 medium potatoes
Can of cream of mushroom soup
1/2 medium onion
1/2-3/4 cup sour cream
Parmesan cheese
Salt and pepper to taste

Peel and cut the potatoes up into small pieces and put in a pan of water to boil. Brown ground meat with onions.

When meat and potatoes are done, stir in the can of soup, sour cream, salt and pepper, and enough of the potato broth to make it moist but not watery. Spoon the mixture out into a casserole dish, sprinkle liberally with Parmesan cheese and bake about 15 minutes or so.
