This Greek-style marinade has strong flavors to complement the strong flavor of lamb. Buy a boneless leg that's been butterflied, or rolled and tied. Unroll it for the marinade to get in everywhere then re-rolling it for even cooking and tenderness. If you happen to buy it with the netting try to save the netting to replace it after marinating. You can grill this flat on the grill as well. This lamb sliced thin is great to make gyro's with!
