Combine first 8 ingredients in a saucepan; bring to a boil. Reduce heat, and simmer 5 minutes; let cool. Pour mixture into a shallow dish; add chicken, tossing gently to coat. Cover and marinate at least 1 hour in the refrigerator, stirring mixture occasionally. Remove chicken from marinade, reserving marinade. Alternate chicken, pineapple, green pepper, mushrooms and tomatoes on 12 (7-inch) skewers. Grill over hot coals 20 minutes or until done, turning and basting frequently with marinade. Serve over hot cooked rice. Recipe by: Southern Living, July 1985 Posted to MC-Recipe Digest V1 #606 by DarlingCL@aol.com on May 12, 1997
