Step 1

For the marinade: Combine the soy sauce, oil, sugar, ginger, sesame oil, sesame seeds, garlic and 1/2 teaspoon salt in a large resealable plastic bag. Add 4 boneless skinless chicken breasts or 8 boneless skinless thighs (about 1 1/2 pounds), squeeze out the air, seal tightly and massage gently to coat the chicken with marinade. Refrigerate for 2 hours or freeze up to 1 month; defrost in the refrigerator overnight before cooking.

Step 2

To cook: Remove the chicken from the bag, letting any excess marinade drip off, and transfer to a foil-lined baking sheet. Broil, turning halfway through, until lightly charred, cooked through and an instant-read thermometer registers 165 degrees F, about 12 minutes.
