Creating Easy Persian Saffron Chicken Kabob is simple when you follow these steps:

1. Prepare Saffron: In a small bowl, steep saffron threads in boiling water for about 10 minutes until the color is vibrant.
2. Make Marinade: In a large bowl, combine yogurt, lemon juice, olive oil, minced garlic, cumin, salt, and pepper. Add the saffron water and mix well.
3. Marinate Chicken: Add the chicken cubes to the marinade, ensuring they are well coated. Cover and refrigerate for at least 1 hour or overnight for maximum flavor.
4. Soak Skewers: If using wooden skewers, soak them in water for 30 minutes to prevent burning during grilling.
5. Preheat Grill: Preheat your grill to medium-high heat.
6. Skewer Chicken and Vegetables: Thread the marinated chicken, onion wedges, and optional bell peppers onto the skewers, alternating as desired.
7. Grill Kabobs: Place the skewers on the grill and cook for 15-20 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.
8. Check Doneness: Ensure the internal temperature of the chicken reaches 165°F (75°C) for safety.
9. Rest Kabobs: Once cooked, remove the kabobs from the grill and let them rest for a few minutes.
10. Serve: Garnish with fresh herbs, if desired, and serve warm.

These straightforward steps will help you create an incredible dish that everyone will enjoy!
