1 lb. hamburger
1/2 c. chopped onion
1 can mushroom soup
1 (16 oz.) can green beans, drained
3 med. potatoes, peeled & quartered
1 beaten egg
Milk
1/2 c. shredded American cheese

In large skillet cook hamburger and onion until meat is browned and onion is tender; drain off fat. Stir in beans, soup, 1/4 cup water, 3/4 teaspoon salt and 1/8 teaspoon pepper. Turn mixture into a 1 1/2 quart casserole.

In a covered pan cook potatoes in boiling salted water about 20 minutes or just until tender, drain. Mash while hot, stir in egg. Add enough milk to make potatoes fluffy, yet stiff enough to hold their shape. Season with salt and pepper. Drop potatoes in mounds atop meat mixture. Sprinkle with cheese. Bake at 350 degrees, uncovered, for 25 to 30 minutes or until heated through. Makes 4 to 6 servings.
