PLACE steak and combined vegetables in separate shallow dishes. Pour 1/4 cup marinade over ingredients in each dish; turn to evenly coat all ingredients. Refrigerate 30 min. to marinate.
HEAT grill to medium heat. Remove steak and vegetables from marinade; discard marinade.
GRILL steak 8 to 10 min. on each side or until medium doneness (160°F). Meanwhile, grill vegetables 3 to 4 min. on each side or until crisp-tender.
