Cut the paneer and onion into 1 inch cubes. Deseed and chop the peppers into 1 inch pieces too.
Take Greek yogurt in a bowl. Add red chili powder, turmeric powder, kasoori methi, tandoori masala, salt, chaat masala and aamchur.
Stir till smooth.
Add the paneer and vegetable pieces and coat them with the seasoned yogurt. Set aside for 30 minutes (or more).
Using skewers or toothpicks, skew the peppers, onions and paneer pieces ensuring the marinade goes with the pieces on to the skewers.
Preheat the Air Fryer at 400 F. Line the basket with some foil or parchment paper. Once the air fryer is hot, place the skewers in it ensuring there is space between them. Spray some oil on top.
Let the skewers cook for 7 minutes, flipping them once in about 4-5 minutes. The paneer, peppers and onions should have some brown spots by then.
Remove from the basket and serve with cilantro chutney. Top the skewers with chaat masala and lime juice.
