Drain, rinse and grind moong or other lentil to a fine paste with water as required (it will depend on the lentil or bean used). Add ginger-green chilli paste and salt and mix well. Transfer to a bowl. There is no need to ferment the batter. Heat a tawa (pancake griddle), spread a ladleful of batter into a round chilla (like a small crepe), cover and cook until the underside is a light golden colour. Turn it over and cook the other side until it is equally done. Serve hot.
