Combine soy sauce, garlic salt, honey, and minced garlic (and sliced green onions if using) in a gallon-size resealable bag and mix until blended.
Add the chicken pieces to the bag, seal, and toss to coat thoroughly in the marinade.
Marinate the chicken in the refrigerator for at least a few hours (longer for more flavor).
Preheat the oven to 425°F (218°C). Lightly grease a baking dish.
Place the marinated chicken in the prepared baking dish and pour the remaining marinade over the pieces.
Bake the chicken for 30 minutes, then turn each piece and baste with the pan marinade.
Return the chicken to the oven and bake an additional 10–15 minutes, until cooked through and juices run clear (internal temperature 165°F / 74°C).
Sprinkle sesame seeds over the chicken if desired and serve warm over rice or noodles.
