Middle Eastern Grilled Lamb

5 pounds boned lamb roast
4 tablespoons minced garlic
2 teaspoons ground cinnamon
1 tablespoon ground allspice
1 cup fresh mint leaves, torn
1/4 cup extra virgin olive oil
1. Prepare a grill.
2. Place lamb in a 13 x 9-inch microwave-safe baking dish.
3. In a small bowl, mix together garlic, cinnamon, allspice, mint
and olive oil. Spread evenly over the lamb. Cover and
microwave on medium for about 20 minutes, or until the internal
temperature reaches 110° to 120°F.
4. Remove the lamb to a grill and cook on medium-high until the
surface blackens and the meat is tender (a meat thermometer
should register 155° for medium doneness). Let stand for at least
10 minutes before carving.
Makes 10 servings.
