Many people use bread crumbs, oatmeal, rice or saltine crackers to bind ground beef. You can soak bread slices in milk, too. Use three slices of bread and 1/3 cup of milk for 3 pounds of ground beef. Add 1-1/2 Tablespoons Worcestershire sauce and 2 Tablespoons ketchup to the mix, too. Add desired seasoning such as salt, pepper, garlic.
