Blend orange juice with hoisin sauce and ginger. Place chicken and half of sauce in a resealable bag. Marinate in the refrigerator for at least 30 min. or for up to 24 hours.
Preheat grill to medium-high. Remove meat from marinade and pat dry with paper towels; discard used marinade. Brush chicken lightly with oil.
Grill chicken for 2 min. Brush evenly with fresh marinade, reduce heat to medium and grill, turning and basting often, for 10 to 12 min. longer or until the chicken is cooked through. Sprinkle with green onions and sesame seeds before serving.
