Arrange the chunks of chicken, squash, bell pepper, and onion evenly onto skewers (we used metal grilling skewers, but if you use wooden, you'll need to soak them in water for 30 minutes prior to grilling).
To make the glaze, mix together the soy sauce, honey, brown sugar, worcestershire sauce, and sesame oil together in a bowl.
Preheat the grill to medium-high heat.
Place the skewers on the grill and brush with the glaze. While you're cooking, baste the skewers with the glaze every couple of minutes.
Allow to cook for 5-6 minutes on each side until the chicken is cooked through (165 internal temperature). Remember to keep basting.
Serve with rice or a salad!
