Grilled Leg Of Lamb With Yogurt-Mint Sauce

• 1 yellow onion, peeled and quartered
• 7 garlic cloves, peeled
• 2 tablespoons fresh rosemary, roughly chopped
• 1/2 cup lemon juice
• 2 1/2 teaspoons salt
• 2/3 cup olive oil
• 4 -5 lbs leg of lamb, boned and butterflied, and trimmed of fat (I get the butcher to do this for me)
• 1 red onion, peeled and thinly sliced
• 2 bunches radishes, rinsed and trimed
• Yogurt mint sauce
• 1/4 cup whole plain yogurt
• 1 garlic clove, minced
• 2/3 cup fresh mint leaves
• 1 teaspoon salt
• 1 teaspoon lemon juice
• 1/4 teaspoon fresh ground black pepper
• 1/8 teaspoon cayenne
• 3/4 cup whole plain yogurt, additional

1. In a blender, whirl yellow onion, garlic, rosemary, lemon juice, and salt. With blender running, slowly pour in olive oil.
2. Rinse lamb and pat dry. With a small knife, make small slashes (1 inch long and 1 inch deep) all over the lamb, and put it in a nonreactive dish. Coat lamb with onion marinade, making sure the mixture gets into the slits. Cover and chill 2 hours or up to overnight, turning occasionally.
3. Remove lamb from refrigerator about 1 hour before you plan to cook it. Spread lamb flat on an oiled barbeque grill over a solid bed of medium-heat on a gas grill (you can hold your hand 1 to 2 inches above grill level only 4 to 5 seconds.). Close lid. Cook lamb, turning once and brushing with marinade, until a thermometer inserted in center of thickest part registers 140 degrees, about 40 minutes.
4. Transfer meat to a platter and cover. Let rest 15 to 20 minutes. Thinly slice meat, garnish with sliced red onion and radishes, and serve with yogurt-mint sauce.
5. Yogurt-Mint Sauce:
6. In a blender whirl all ingredients until smooth. Transfer to a serving bowl and stir in an additional 3/4 cup plain whole plain yogurt. Makes about 1 cup sauce.
