Cut the chicken in small pieces, about 1.5 inch cubes. In a medium bowl, whisk together all ingredients except chicken. Add the chicken to the bowl so marinade covers each piece of chicken. Cover (preferably with a beeswax food wrap) and place in fridge. Marinate for at least 2 hours.
Heat your Cookswell oven. Remove chicken from fridge and thread on wooden skewers. On each skewer add 2 pieces chicken, 2 pieces of zucchini, 1 stack of onion, use whatever ordering is desired. Continue threading the skewers until all chicken and vegetables have been used. Save leftover marinade for basting.
Place chicken skewers on grill and turn every couple of minutes or so while brushing on some marinade. Grill until chicken is cooked through, about 15-20 minutes. Garnish with cilantro and serve. Cook with soul. Eat with pleasure!
