1/3 cup low-sodium soy sauce
2 tablespoons toasted-sesame oil
1 tablespoon honey
1 tablespoon unseasoned rice vinegar
1 teaspoon freshly ground pepper
3 scallions, thinly sliced
3 garlic cloves, minced
1 tablespoon finely grated fresh ginger
2 tablespoons toasted sesame seeds
1 1/2 pounds chicken breast cutlets, pounded 1/3 inch thick
Vegetable oil, for brushing
In a resealable plastic bag, combine the soy sauce, sesame oil, honey, vinegar, pepper, scallions, garlic, ginger and 1 tablespoon of the sesame seeds. Add the chicken and turn to coat. Seal the bag and refrigerate for at least 2 hours or for up to 4 hours.
Light a grill or preheat a grill pan. Oil the grates. Remove the chicken from the marinade and brush lightly with oil. Grill over moderate heat, turning once, until lightly charred and cooked through, 5 minutes. Sprinkle with the remaining 1 tablespoon of sesame seeds, thinly slice and serve.
