Marinated in spiced yoghurt, Kashmiri chillies, and garlic, then roasted over roaring tandoor charcoal embers with charred edges.
Wipe the mushrooms clean and brush the caps and outsides with a little mustard oil.
Fry the onion and green chili in the remaining oil until soft, then mix with the paneer, garam masala, chaat masala and salt.
Pile the spiced paneer filling into each mushroom cap.
Grill the stuffed mushrooms over medium heat (or in a hot tandoor) for 8-10 minutes until tender and lightly charred.
Serve hot straight off the grill with mint chutney.
