In a large bowl, mix 200 grams of hung curd, 1 tablespoon of ginger-garlic paste, 2 teaspoons of black pepper powder, 1 teaspoon of garam masala, 1 teaspoon of chaat masala, 1 tablespoon of lemon juice, and salt to taste. Mix well to form a smooth marinade.
Cut 500 grams of boneless chicken into bite-sized pieces and add them to the marinade. Mix well, ensuring that the chicken pieces are well coated. Cover and refrigerate for at least 2 hours or overnight for better results.
Preheat a grill or oven to 200°C. Skewer the marinated chicken pieces onto metal or pre-soaked wooden skewers, leaving some space between each piece.
Place the skewers on the grill or in the oven and cook for 15-20 minutes, turning occasionally, until the chicken is cooked through and slightly charred on the edges.
Remove the skewers from the grill or oven and let them rest for a few minutes before serving. Garnish with chopped coriander leaves and serve with mint chutney or yogurt dip.
