In a medium bowl stir together plum tomatoes, sun-dried tomatoes, chopped basil, and cayenne; set aside. In a small bowl combine mustard, honey, and garlic. Rub mustard mixture over all surfaces of chops.
Place chops on a kettle-style grill over medium-hot fire and grill for 3-4 minutes. Turn chops and grill for 3-4 minutes more or until chops are just done. Serve with tomato salsa. If desired, garnish with basil sprigs.
