How to make it
Combine all ingredients for the soy marinade. Place chicken thighs in marinade and refrigerate for three-to-four hours.
Heat grill to medium-to-high and cook until an instant read thermometer reads 165° Fahrenheit. (In the winter, you can cheat and use your oven broiler on medium-to-high.)
Allow meat to rest for five minutes. Slice meat and place on top of lettuce leaf. Serve with red onion, chives, and toasted sesame seeds. Place on top.
