Directions

1. Set strainer over large bowl. Line strainer with 2 layers of cheesecloth (do not let strainer touch bottom of bowl). Spoon yogurt into strainer.

3. Mix yogurt, garlic and lemon juice in small bowl. Season to taste with salt.
4. Rub cumin and coriander over lamb pieces. Thread lamb onto 6 metal skewers. (Yogurt and lamb can be prepared 4 hours ahead. Cover separately and chill.)
5. Combine 1 cup water and 1/4 teaspoon salt in medium saucepan. Bring to boil.
6. Add couscous.
7. Remove from heat. Cover; let stand until liquid is absorbed, about 5 minutes.
8. Transfer couscous to large bowl; fluff with fork. Cool to room temperature. Stir in chopped cucumber, tomato, onion, olive oil and fresh dill. Season with salt and pepper.
9. Prepare barbecue (medium-high heat). Grill lamb to desired doneness, turning frequently, about 10 minutes for medium-rare.
10. Transfer to platter.
11. Sprinkle with salt. Grill pitas until heated through and lightly toasted, about 1 minute per side.
12. Place 1 pita on each of 6 plates.
13. Spread yogurt mixture evenly over pitas. Spoon couscous down center of pitas. Slide lamb off skewers onto couscous.
