Shepherd's Pie

Another recipe from a friend.  I would halve it next time I make it; it's filling and we had several leftovers, so maybe I won't...  :)

1 lb. hamburger

6-8 large potatoes, mashed

2 cans tomato soup

1 can green beans

1 can corn

1/4 cup onion chopped

grated cheese

Brown hamburger with onion and drain.  In casserole dish mix beans, corn, tomato soup and browned hamburger.  Cook and mash potatoes and place over meat mix.  Cook at 350 for 25 minutes.  Sprinkle with cheese when cooked.
