Heat grill. In small saucepan, combine all glaze ingredients; mix well. Bring to a boil over medium heat. Boil 1 minute, stirring constantly.
When ready to grill, lightly brush glaze on one side of each chicken breast half. Place chicken, glaze side down, on gas grill over medium heat or on charcoal grill 4 to 6 inches from medium coals. Lightly brush glaze over chicken; cook 5 to 8 minutes.
Turn chicken; cook an additional 5 to 8 minutes or until fork-tender and juices run clear. Bring any remaining glaze to a boil; serve with chicken.
