Cover and refrigerate at least four hours, preferably overnight. Drain burghul. Mix with other ingredients. Chill until needed. Thread lamb pieces onto skewers - which have been soaked in water to prevent them burning - alternating with vegetables. Baste with marinade and grill or barbecue - taking care not to overcook the meat. Serve with Tabbouleh salad and flat pitta bread. Serve with Hazelnut Cream Dressing. Leftover potential: Poor.
