Place the chicken into a zip-lock bag or a container. Add the chicken, give the container/bag a good shake, ensuring that the marinade is covering all the chicken chunks. Place in the fridge for up to 2 hours.
Cut the peppers and zucchini into chunks. About 1-inch squares or at least the size of the chicken chunks. Try to keep the pieces the same size for even cooking.
Place the chicken, peppers and zucchini onto the skewers. (Soak wooden skewers in water 30 minutes before use)
Either place under the grill or on the BBQ and cook for 10-15 minutes, turning over to ensure even cooking, until the chicken is cooked and golden in colour. Baste with the remaining marinade to keep the kebabs moist.
