This sweet and sour hamburger steak and gravy is a great comfort food. My family loves it.1 pound ground beef 1 egg 1/2 teaspoon salt 1/4 teaspoon pepper 1/2 teaspoon garlic powder 1 teaspoon minced onion 1/2 cup quick oats 1/2 teaspoon Italian seasoning or oregano 2 tablespoons oil 2 tablespoons brown sugar 2 tablespoons flour 1/4 cup onion, finely chopped 1 (8 ounce) can tomato sauce 1 (4 ounce) can mushroom stems and pieces, drained 1/4 cup green pepper, chopped 1 teaspoon Worcestershire sauce 1 tablespoon Dijon mustard 1/2 cup water In a mixing bowl combine the ground beef, egg, salt, pepper, garlic powder, minced onion, oats and Italian seasoning. Make into patties. (I usually make 4 patties out of a pound of hamburger). Brown the hamburger patties in the oil in a skillet. Drain. Mix together the brown sugar, flour, onion, tomato sauce, mushrooms, green pepper, Worcestershire sauce, Dijon mustard, and water. Pour over the hamburger steaks in the skillet and simmer for about 20 to 25 minutes. If you need more liquid, add a little more water. Makes 4 servings. Serve the gravy over mashed potatoes, rice, or pasta. Enjoy! Click to follow The Southern Lady Cooks on Facebook.
