Cube chicken and add ½ cup of sauce to the chicken. Mix to coat the chicken then marinate in the refrigerator for at least 30 minutes up to overnight.
While the chicken marinates, soak the bamboo skewers and cook rice if desired.
Thread the marinated chicken onto the bamboo skewers and place them onto a plate.
Heat your grill then grill the chicken skewers for 3-4 minutes on each side.
To serve, place the grilled chicken skewers onto a bed of butter lettuce, drizzle with the reserved sauce and garnish with sliced scallion and sesame seeds.
