Creating Grilled Tandoori Chicken can be straightforward with the following steps:

1. Prepare the Marinade: In a large bowl, combine the Greek yogurt, vegetable oil, lemon juice, ginger, garlic, salt, cumin, coriander, cayenne pepper, smoked paprika, turmeric, and garam masala. Mix thoroughly until the ingredients are well blended.

2. Marinate the Chicken: Add the chicken pieces to the marinade, ensuring they are well coated. Cover the bowl with plastic wrap or transfer to a sealable bag. Refrigerate for at least 1 hour or up to overnight for the best flavor.

3. Prepare the Grill: Preheat your grill to medium-high heat. Make sure the grates are clean to prevent sticking.

4. Remove Chicken from Marinade: Take the chicken out of the refrigerator and let it sit at room temperature for about 15 minutes before grilling.

5. Grill the Chicken: Place the chicken pieces on the preheated grill. Cook for about 6-8 minutes per side, or until the internal temperature reaches 165°F (75°C) and the chicken is beautifully charred.

6. Check for Doneness: Use a meat thermometer to ensure the chicken has reached the appropriate internal temperature. If needed, grill for a few more minutes.

7. Rest the Chicken: Once cooked, remove the chicken from the grill and let it rest for about 5-10 minutes. This allows the juices to redistribute, making the chicken more tender.

8. Garnish: If desired, sprinkle chopped fresh cilantro over the grilled chicken before serving.

By following these steps, you’ll have an incredible dish that not only tastes amazing but looks visually stunning.
