Cube the chicken breast into bite-sized pieces and place them in a ziplock bag.
In a small bowl, mix olive oil, Kinder’s Woodfired Garlic rub, Worcestershire sauce, balsamic vinegar, and red pepper flakes (if using).
Pour the marinade over the chicken, seal the bag, and massage to coat evenly. Refrigerate for 2–4 hours.
In a separate ziplock bag, combine the sliced zucchini, squash, quartered onions, cherry tomatoes, and halved sweet peppers.
In a small bowl, whisk together olive oil, balsamic vinegar, Holy Voodoo rub (or Cajun rub), honey, salt, and pepper.
Pour the veggie glaze over the vegetables, seal the bag, and gently toss to coat. Let sit for 15–30 minutes.
Preheat the wood pellet smoker to 350°F.
Thread the marinated chicken and glazed vegetables onto long metal skewers, alternating items for variety and even cooking.
Place skewers on the grill grate and smoke at 350°F for 30 minutes, turning every 5–6 minutes for even charring.
Use pliers to remove skewers from the grill when done.
Check internal temperature of chicken with a meat thermometer; it should read 165°F before removing from heat.
Serve hot, directly from the skewers or over rice, couscous, or salad.
