In large shallow dish, whisk together vinegar, mustard, soy sauce, rosemary, oil and garlic; add lamb chops in single layer, turning to coat well. Cover and marinate in refrigerator for at least 2 hours or up to 8 hours, turning occasionally.
Discarding marinade, place chops on greased grill over medium-high heat; cook for about 5 minutes per side for medium-rare or to desired doneness. Transfer to platter; tent with foil and let stand for 5 minutes. Makes 4 servings. Typed in MMformat by cjhartlin@msn. Com
