In a bowl, combine the steak sauce and 2 tablespoons of coating mix. Crumble beef over mixture and mix well. Shape into four 3-1/2-in. patties. Dip both sides of patties in remaining coating. Place on an ungreased baking sheet.
Bake at 350° for 20 minutes or until a thermometer reads 160° and juices run clear, turning once. Serve on buns with lettuce. Yield: 4 servings.
