Combine the channa dal, green chillies and 2 tbsp of water in a mixer and blend in a mixer to a coarse paste. Transfer the paste into a bowl, add all the remaining ingredients and mix well. Divide the mixture into equal portions and keep aside. Heat a non-stick tava and grease it using little oil. Shape a portion of the mixture into a flat round Tikki and immediately cook it on the tava on a slow flame using little bit oil, till it turns golden brown in color from both the sides. Serve hot with green chutney.
