Creating Grilled Spicy Tandoori Chicken is straightforward if you follow these simple steps:

1. Prepare Marinade: In a large bowl, combine yogurt, vegetable oil, lemon juice, garlic paste, ginger paste, garam masala, tandoori masala, paprika, turmeric powder, chili powder, cumin powder, and salt. Mix well.
2. Marinate Chicken: Add the chicken pieces to the marinade, ensuring each piece is well coated. Cover and refrigerate for at least 1 hour, preferably overnight for maximum flavor.
3. Preheat Grill: Preheat your grill to medium-high heat. If using charcoal, allow the coals to ash over.
4. Prepare Chicken for Grilling: Remove the marinated chicken from the refrigerator. Allow it to come to room temperature for about 15 minutes.
5. Grill Chicken: Place the chicken pieces on the grill. Cook for 20-30 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks. Use a meat thermometer to ensure the internal temperature reaches 75°C (165°F).
6. Baste (Optional): While grilling, you can baste the chicken with any remaining marinade for added flavor.
7. Rest: Once cooked, remove the chicken from the grill and let it rest for 5 minutes to allow the juices to redistribute.
8. Garnish: Serve with fresh cilantro and lemon wedges for an added burst of flavor.
