Follow these simple steps to create your Grilled Asian Chicken Skewers:

1. Prepare the Marinade: In a bowl, whisk together soy sauce, sesame oil, honey, minced garlic, grated ginger, rice vinegar, and sriracha (if using).
2. Marinate the Chicken: Place the cubed chicken in a resealable plastic bag or a bowl. Pour the marinade over the chicken, ensuring all pieces are coated. Seal the bag or cover the bowl and refrigerate for at least 20 minutes (or up to 2 hours for more flavor).
3. Preheat the Grill: Preheat your grill to medium-high heat, around 400°F (200°C).
4. Prepare the Skewers: If using wooden skewers, soak them in water for 30 minutes to prevent burning. Thread the marinated chicken, bell pepper, onion, and zucchini onto the skewers, alternating the ingredients for a colorful presentation.
5. Grill the Skewers: Place the skewers on the grill and cook for 10-15 minutes, turning occasionally until the chicken is cooked through and has nice grill marks.
6. Check for Doneness: Ensure the chicken reaches an internal temperature of 165°F (75°C) for safe consumption.
7. Remove from Grill: Once cooked, carefully remove the skewers from the grill and let them rest for a few minutes.
8. Garnish: Sprinkle with chopped green onions and sesame seeds before serving.
