Sort the spinach, wash and drain. Peel and finely chop the onion and garlic. Wash and chop the mint. Heat olive oil. Fry garlic and onion.
Add the spinach and allow to completely collapse. Season with salt, pepper and mint. Drain again if necessary. Shape into small balls (preferably with the help of an ice-ball scoop).
Grate the parmesan and turn the balls in it. Serve with pickled peppers.
