In a large bowl combine the spinach, egg, ricotta, parmesan, salt and pepper. Mix well. Shape into balls (1 heaping tablespoon of the mixture); roll each in flour and drop (about 5 at a time) into 3 quarts of boiling water. When the balls float to the top, boil for 5 minutes. Lift balls out gently with a slotted spoon; place in a serving dish. Repeat until all the balls have been cooked. Heat the marinara sauce and pour over, sprinkle with additional cheese.
