5 limes, divided
1/2 cup KRAFT Original Barbecue Sauce
4 boneless pork chops (1 lb.)
Squeeze juice from 1 lime; mix with barbecue sauce. Pour 1/4 cup over chops in shallow dish; turn to evenly coat both sides of each chop. Refrigerate 15 min. to marinate. Meanwhile, heat grill to medium heat. Cut each of the 4 remaining limes into 4 slices. Remove chops from marinade; discard marinade. Place 8 lime slices on grill grate; top with chops. Brush with some of the reserved sauce. Grill chops 5 min. ; turn. Add remaining lime slices to grill. Cook 8 to 12 min. or until chops are done (145 degrees F), turning chops and limes occasionally and brushing with the remaining sauce. Remove chops and limes from grill. Let stand 3 min. Discard lime slices from under chops. Serve chops with remaining grilled lime slices.
