These spicy tandoori chicken skewers are a perfect appetizer or main course for any occasion. Using a food processor, you can easily make the marinade by blending together yogurt, garlic, ginger, chili powder, garam masala, and other spices. The chicken is then coated in the marinade and threaded onto skewers. Grilling the skewers gives the chicken a charred and smoky flavor, while keeping it moist and tender. Serve these spicy tandoori chicken skewers with a cooling cucumber raita and some lemon wedges for a delightful and flavorful meal.
