Cut all the vegetables in equal proportion. Chop coriander leaves, green chilies finely. Heat oil in a pan, add mustard seeds and allow it to splutter. Add turmeric, green chilies and fry for few seconds, now add all the cut vegetables. Cover the pan with a lid and allow the vegetables to become tender, also add salt so it mixes evenly with vegetables. Meanwhile mix the gram flour with water and make a semi liquid batter. Add the batter to the vegetables once it’s cooked. Boil the mixture for few minutes until the raw smell of gram flour disappears (approx 7-8 minutes). Garnish with cilantro/coriander and enjoy it with chapathi or poori.
