Use the preparation: lightly grease the outside of a small bowl with oil (katori) that can be used in a microwave. Set it aside.
Pick one papad and put it in a plate of water for a duration of 2 seconds, only until it becomes slightly soft. Take it off and dry it with paper towels to get the excess water.
Fill the papad with water and cover the katori with the moistened soft papad. Press the centre to shape and crease the sides around the bowl to create a cup.
Put the katori (and papad on it) in the microwave and cook under HIGH for 60 seconds. In case it is still a little soft, add 30 more seconds until it is crisp and will maintain its shape.
Cool down for a few seconds and then carefully use a knife to run around the rim to loosen the papad in the bowl. Repeat the same with all katoris.
Add the chickpeas, onions, tomatoes, green chilies and cilantro into a large mixing bowl. Add the red chilli powder, cumin powder, amchur, and salt.
Add lemon juice when it is time to eat. Put 2-3 tablespoons of the filling into each papad dish. Serve with boondi, fine sev, and cilantro. Serve immediately!
