In a small bowl combine together olive oil, vinegar, mint and garlic; whisk until smooth. Pour over lamb and marinate in the refrigerator for 2 hours.
Preheat grill.
Remove lamb chops from marinade and season with salt and pepper. Lightly oil grill right before cooking chops. Grill until desired doneness is reached, about 6 minutes per side for medium-rare. Serve warm.
