Thread the chicken, zucchini, red bell peppers, and red onion onto skewers, alternating between each ingredient. Season the skewers with salt and pepper.
Melt the Garlic Better Butter in a small saucepan or in the microwave.
Brush the skewers with the melted butter.
Place the skewers on the grill and cook for 10-12 minutes, turning occasionally, until the chicken is cooked through and the vegetables are tender and slightly charred.
Remove the skewers from the grill and let them rest for a few minutes.
Serve the grilled chicken and veggie skewers with any remaining Garlic Better Butter for dipping. Enjoy!
