Harrah's Bar B Que Hamburgers

• 3/4 cup Quakers Rolled Oats
• 4 tablespoons granulated sugar
• 1 1/2 pounds extra lean ground beef
• 4 tablespoons Worcestershire sauce
• 6 tablespoons apple cider vinegar
• Sauce
• Salt and pepper to taste
• 1 cup milk
• 1 cup water
• 3 tablespoons chopped onion or dried minced onion
• 2 cups Heinz ketchup

Mix well and pour over prepared patties. Bake uncovered at 325 degrees F for 1 to 1 1/2 hours. Serve on hamburger buns. (If you double meat ingredients you should have enough sauce to cover all). Can also shape meat into small meatballs and serve as an appetizer.
