Lamb Kabobs with Yogurt Sauce

1/2 cup white wine or chicken broth
2 tablespoons olive oil
2 teaspoons ground coriander
1 teaspoon ground ginger
1/2 teaspoon salt
1/4 teaspoon ground cinnamon
1/2 pound sirloin lamb roast, cut into 1-inch cubes
1/2 cup plain yogurt
6 medium fresh mushrooms
1 medium zucchini, cut into 1/2-inch slices
1-1/2 cups hot cooked couscous

In a small bowl, combine the first six ingredients. Pour 1/3 cup marinade into a large resealable plastic bag; add lamb. Seal bag and turn to coat; refrigerate for 15 minutes.
Pour 1 tablespoon marinade into a small bowl. Stir in yogurt; cover and refrigerate. Cover and refrigerate remaining marinade for basting. Drain and discard marinade from lamb. On two metal or soaked wooden skewers, alternately thread lamb, mushrooms and zucchini.
Grill kabobs, covered, over medium heat for 5-6 minutes on each side or until lamb reaches desired doneness (for medium-rare, a meat thermometer should read 145°; medium, 160°; well-done, 170°), basting frequently with reserved marinade. Serve with couscous and yogurt mixture. Yield: 2 servings.
