1 lb. ground beef, browned with onion
2 lg. potatoes, thinly sliced (I use more)
1 can mushroom soup
1 1/4 c. milk
1/4 tsp. pepper
1 1/4 c. Wheaties or crackers, crushed
1 c. sour cream
1 tsp. salt
1 c. shredded Cheddar cheese

Pour beef into 9 x 13 inch pan. Arrange potato slices on meat. Stir together soup, sour cream, milk, salt and pepper. Pour over potatoes. Sprinkle with cheese and crumbs. Bake uncovered at 350 degrees for 1 1/2 hours or until potatoes are tender.
