Shepherd's Pie Casserole

I was skeptical about this casserole at first since it called for cream of mushroom soup because I hate mushrooms. Fortunately, my husband and I really liked it! (Especially when you stir it all up before you eat it.)

1-2lb ground beef/turkey (turkey's better for you!)
2 cans green beans, drained
2 cans cream of mushroom soup (Next time I'm going to try white gravy and see how that turns out.)
2-4c mashed potatoes
2c shredded cheese

Brown meat; drain. Put it in the bottow of a greased 9x13 casserole dish. Layer green beans, soup, potatoes, then cheese in that order. Bake at 350 degrees for about 20 minutes until the cheese is melted and soup is bubbly around the edges.
