Take about 3 tbsp peanut sauce, mix with 3 tbsp sweet soy sauce, and pour enough water, and make chicken marinade. More or less of the sauce is up to you, and adjust the sweet soy sauce and water. In other word, if you’d like stronger flavor but not too thick marinade, add more sauce, adjust water and soy sauce.
Slice chicken into cubes, and thread them onto the soaked skewers.
Coat chicken in the marinade and let sit before grilling.
Grill chicken until cooked through, brushing with marinade as needed.
Serve grilled chicken with peanut sauce and warm rice.
