Wash sabudana in water. Drain, then sprinkle a little water on it, and set aside for an hour. Heat ghee in a thick bottom vessel (it is hot enough if a little jeera added to it starts sputtering). Why the green chilies and jeeea for a minute. Add the potato and fry for a few minutes. Add salt and peanut powder to the Sabudana. (A little sugar, too, if you like the taste). Add this sabudana on the potatoes and fry. Let the mixture cook for about 10 min. Stir occasionally and sprinkle a little water if it is dry. Garnish with grated coconut and serve hot.
