Marinated in spiced yoghurt, Kashmiri chillies, and garlic, then roasted over roaring tandoor charcoal embers with charred edges.
Whisk the yogurt with ginger-garlic paste, Kashmiri chili powder, garam masala, turmeric, lemon juice, and salt; coat the paneer, pepper, and onion and rest for 30 minutes.
Thread the paneer and vegetables onto skewers, alternating pieces.
Cook on a hot tandoor, grill, or tawa, turning and basting with oil, until the edges char lightly.
Slide off the skewers and serve hot with mint chutney and onion rings.
