MIX first 3 ingredients. Reserve 1/4 cup sauce for later use. Pour remaining sauce over chops in shallow dish; turn chops over to coat both sides of each. Refrigerate 15 min. to marinate.
HEAT barbecue to medium-high heat. Remove meat from marinade; discard marinade. Thread meat onto 8 skewers alternately with pineapple, peppers and onions.
GRILL 12 to 14 min. or until meat is done, turning occasionally and brushing with reserved sauce.
