Peel the potatoes, then roughly chop them. Put them in a pot and cover them with cold water. Bring the water to a boil, then reduce it to a simmer. Cook the potatoes until they're completely soft, and a fork slides through them easily. Drain the water. Mash the potatoes roughly with a fork. Put the red chili powder,chopped green chilli,chopped onions, chat masala and coriander leaves in the pot with the potatoes.  Add a pinch of salt. Use a fork to mash the spices in with the potatoes to thoroughly distribute them. Taste the mixture and add more spices or salt if you wish. Stir in the  and chickpeas with a spoon, so that everything is completely mixed. If you wish, add a few drops of oil to moisten the filling. It doesn't need too much moisture, though, since you'll be adding pani as the finishing touch
