This is an excellent recipe to use with leftover mashed potatoes! It's quick and easy! I like that it's a one dish meal; a great casserole!
1 pound hamburger
1 small onion, diced
salt & pepper
3 tablespoons featherlight flour
2 cups water
3 beef bouillon cubes
1 quart green beans, drained
Preheat oven to 375º. Brown hamburger and onions, seasoning with salt and pepper. Sprinkle flour on top of cooked meat. Stir and cook for 1 - 2 minutes. Pour in water and stir. Add beef bouillon cubes. Stir every minute or two, until thickened. Add green beans, and mix together until heated through. Pour beef and green bean gravy into a greased 9 x 13 inch casserole dish. Top with mashed potatoes. Bake at 375º for about 20 minutes, or until potatoes are heated through. Remove from the oven, and immediately top with shredded cheddar cheese.
