This was one of my favorite childhood dishes. You can use ground beef or leftover Sunday roast.
1 can green beans (drained)
Mashed Potatoes (3-5 cups)
Shredded or chopped roast beef (1-2 cups) - can also use browned ground beef
1 can Campbells Cream of Mushroom Soup
Shredded Cheddar Cheese
In a casserole dish, layer the following: green beans, mashed potatoes, shredded beef, mushroom soup. Bake at 350 degrees for about 30 minutes or until browned and bubbly. Can top with shredded cheddar cheese for the last 5 minutes if desired. Serve with warm rolls and a green or fruit salad.
