As I said earlier clean and wash the leaves and drain out all the excess water. Roughly chop the leaves and keep aside.In a wok heat oil .Add the mustard seeds-cumene seeds-chopped garlic-green chillies and onion in that order and fry for few minutes or till the onion becomes translucent. Add the roasted groundnut powder and then add the chopped leaves. Mix properly and cook covered for few minutes. Add salt once the Tandulka leaves are almost cooked. Cook uncovered for a few minutes more.Serve with Bhakri.
