This is another recipe from my Grandma Ella.
1 lb. round steak, cut into thin strips
1/2 C. chopped onion
1 can mushrooms
1 can tomato soup
1/2 C. water
1/2 C. sour cream
Dredge meat in flour and fry in butter. Add onion, mushrooms, tomato soup and water and simmer until tender. Just before serving add sour cream, heat and serve with wide egg noodles.
