Prepare marinade: In a shallow, glass container, combine all marinade ingredients. Add chicken and onion and toss. Cover and refrigerate for at least 6 hours or overnight.
Remove chicken and onion mixture from refrigerator 30 minutes before grilling. Preheat a grill to medium. Thread skewers, starting with 1 piece each chicken, onion, tomato and baguette. Repeat, then finish with 1 cube chicken. Repeat with remaining skewers.
Grill skewers 5 to 6 minutes each side, until chicken is cooked through. Drizzle skewers with balsamic (if using). Serve hot or at room temperature.
