1. In a small bowl, combine soy sauce, sesame oil, five-spice powder, garlic, crushed red pepper, vegetable oil and cilantro, if desired.
2. Place chicken in a large ziplock bag. In a separate large ziplock bag, combine onion and bell peppers. Divide marinade between bags, seal and gently toss to coat. Refrigerate both bags for at least 45 minutes.
3. Preheat broiler, placing a rack about 5 inches from heat source. Line a large, rimmed baking sheet with foil; mist foil with cooking spray. Thread chicken and vegetables onto 4 metal skewers. Place on baking sheet and broil until chicken is cooked through and vegetables are tender, turning often, about 12 minutes total.
