Now flatten the potato oats mixture and fill with 1 teaspoon sattu mixture.
Now gather from all sides and roll into an oval or a medallion or cylindrical shaped cutlet.
Heat the oil in a deep kadhai/wok and deep-fry, 2 or 3 cutlets at a time, till they turn golden brown in colour from all the sides.
Drain them out on an absorbent paper.
