Long wooden skewers, soaked in water for 30 minutes
Combine first 6 ingredients in a large shallow, glass dish. Add beef cubes and mix well with marinade. Cover and let marinate for 1 hour at room temperature or a minimum of 2 hours to overnight in the refrigerator. Remove beef cubes from marinade, reserving marinade. Alternately thread beef cubes, onion, mushrooms, peppers and pineapple chunks onto prepared skewers. Grill, covered, over medium-hot coals (350* to 400*F) for 10 to 12 minutes or until desired doneness, turning and basting occasionally with reserved marinade. Discard any remaining marinade. Makes 4 to 6 servings. Serve with hot steamed basmati rice.
