Shephard's Pie

I don't really have a recipe for this, but here's how I throw it together:

1 lb. ground beef
1 can tomato soup
1 can green beans
2+ cups mashed potatoes
1 cup grated cheddar cheese

Cook ground beef with tomato soup. Put in a 8x8" pan. Top with green beans, then mashed potatoes, then cheddar cheese. Bake at 350 for 20-30 minutes.
