PREHEAT grill to medium-hot heat. Place chops and vegetables on greased grill.
GRILL chops 6 to 8 minutes on each side or until cooked through and grill vegetables 5 minutes on each side, brushing each frequently with 1/2 cup sauce.
SLICE chops and vegetables into thin strips. Divide filling among warm tortillas. Roll and tuck in sides to create an enclosed wrapper. Serve with remaining 1/4 cup barbecue sauce.
