Remove lamb from marinade. Season well with salt. Sear the lamb over high heat with one tablespoon oil in ovenproof pan. Sear to a dark brown, then turn lamb over, and transfer to the oven for 7 to 10 minutes, for medium rare. Remove from oven, cover with foil, and allow to rest for 5 minutes before slicing.Caramelized Onion Mashed Potatoes:
