If desired, onion can be included on the skewers. To prepare Chicken Souvlaki in the oven, assemble the skewers as directed and place them on a foil-lined baking sheet. Set the broiler to high and position the skewers 4–5 inches from the heat source, broiling for approximately 5–6 minutes per side until the chicken reaches 165°F. Nutritional information assumes only one-third of the marinade is consumed and excludes additional salt.
