For the Stuffing:
Shift wheat flour and chana dal flour. Add salt and oil and make the firm dough. Leave for 1½ hour.
Grate zucchini or bottle gourd. Add a little salt and keep for 1/2 hour. Squeeze out the water from it. Stir fry in a little oil for 5 minutes. Mix sugar, lemon juice and parched rice and stir. Add groundnut granules, green chili paste, garam masala, salt, coriander leaves and mix well. Divide this stuffing into equal parts.
Make 20-22 balls from the dough. Roll out one ball at a time into a puri and fill with the stuffing. Round up and fry in the warm oil. When all the balls are fried serve warm with the chutney or sauce.
