DO-AHEAD TIP: Toast sesame seeds.
Preheat indoor or outdoor grill to MEDIUM.
In a small bowl, combine teriyaki sauce, toasted sesame seeds, and ginger. Carefully brush the grill rack with olive oil.
Place chicken on the grill and cook for 15 to 20 minutes or until juices run clear, turning once after 10 minutes and brushing frequently with sauce mixture.
Discard any remaining sauce mixture.
