Preheat grill for 10 minutes. In medium mixing bowl, combine ground
beef, steak sauce, and seasoned salt. Mix well. Shape into 12 thin
oval patties, each about 6 inches long. In small bowl, blend cream
cheese, horseradish and mustard. Spread about 1 tbsp in center of
each of 6 patties. Top with remaining patties. Press edges to seal.
Grill at Med with hood closed until burgers feel slightly firm, 10-14
minutes, turning over once. Serve in bratwurst buns with lettuce and
tomato.
