This dish originates from the northwestern province of Rajasthan. The green chilies are generally loaded down with bubbled potatoes; in any case, you can make your own fillings for an extraordinary bite.

These can be served for a night nibble or an end of the week breakfast for the most part with some tomato sauce or natively constructed coriander-and-mint chutney.

Large green chilies: 8-10, Oil for frying

Potatoes: 4-5, Garam masala – 1/2 tsp, Red chili powder – 1 tsp, Chaat masala – 1 tsp, Green coriander – 1/2 cup (cut), Salt to taste
