1Place lamb in shallow glass or plastic dish; pour dressing over lamb. Cover and refrigerate at least 8 hours but no longer than 24 hours.
2Remove lamb from marinade; reserve marinade. Thread lamb, onions, pineapple and bell pepper alternately on each of four 15-inch metal skewers, leaving 1/4-inch space between each piece.
3Set oven control to broil. Place skewers on rack in broiler pan. Brush with half of the reserved marinade. Broil with tops 4 to 5 inches from heat about 6 minutes or until lamb is brown. Turn kabobs; brush with remaining marinade. Broil about 5 minutes longer or until lamb is tender. Serve kabobs on rice; sprinkle with parsley.
