In a medium bowl, combine all ingredients except lamb. Mix very well and then smother each piece of meat on every side and place in a large zipper topped plastic bag and place in the refrigerator to marinate for 5 hours or overnight.
At time of cooking, preheat outdoor grill to medium high and remove lamb from refrigerator. Remove from plastic bag and grill for about 4 to 8 minutes per side, depending on thickness, and your preference for your meat.
SERVING SUGGESTIONS: Serve with baked sweet potatoes and a spinach salad. (You can “bake” the potatoes on the grill or in your crock cooker to keep your kitchen cool.)
