1 small onion chopped
garlic to taste
2 1/2 cups water
2 beef bullion cubes
1/8 cup ketchup
1/2 teaspoon salt
1/2 teaspoon mustard
2 Tablespoons flour

Place meat, butter onion and garlic into a fry pan cook until meat is browned. Remove meat

Mix:
water, bullion cube, ketchup, salt, mustard. Stir into onion and garlic to make thick gravy. Add browned meat to gravy. Simmer about 5 minutes. After 5 minutes tir in 1 cup sour cream. Serve with noodles or mashed potatoes.
