In a medium bowl add the left over pongal , rice flour, chopped green chillies, onion and coriander leaves. Add the grated ginger, coriander powder , lemon juice and salt.
Mix all the ingredients. If the mixture is too sticky add little more rice flour ( not too much).
Make medium size patties with it.Now dust both sides of the patties with the rice flour and rava mixture.
Heat up a pan, add some oil and shallow fry the cutlets on both sides.
Cook the cutlets in low-medium flame. That ensures even cooking with out burning the outer part.
Flip the cutlet, add little more oil and cook till lightly crisp on the outide.
Serve the cutlets with a combination of green and tamarind chutney.
Tastes best when eaten hot.
