Heat gas or charcoal grill. Lightly sprinkle both sides of steak with salt and pepper.
When grill is heated, place steak on gas grill over medium heat or on charcoal grill over medium coals; cover grill. Cook 8 to 11 minutes, turning once, until desired doneness.
Meanwhile, in shallow dish, mix remaining ingredients.
Remove steak from grill; cut diagonally across grain into slices. Coat each slice with sauce mixture before placing on individual plates. Spoon any remaining sauce over steak slices.
