Finely chop the spinach and steam-cook it. Mash the boiled potatoes using a spoon. Finely chop onion, ginger and green chili and sauté them. Add spinach and stir well. Remove from fire and add mashed potatoes and salt. Stir thoroughly and divide this mixture into ten parts. Flatten them out into shapes of cutlet and then dip in beaten egg and bread crumbs and deep-fry in hot oil.
