Mix all the ingredients together well in a large bowl and refrigerate to marinate for at least 3 hours, and up to 12 hours. Remove the chicken from the marinate and grill or broil until cooked through, 5 to 10 minutes. To eat, serve with lettuce leaves and steamed rice. Place a bit of rice on a lettuce leaf and top with a piece of grilled dak gui. Roll the leaf up around the filling and eat with your hands.
