Dab meat dry, place between 2 layers of cling film and beat evenly thin with a flattening iron or a pot base.
Cut the schnitzel into quarters, season with salt and spread a thin layer of Harissa. Place about 2 plums next to each other on the bottom edge of each schnitzel quarter. Roll up cutlets. Fix each cutlet with 2 wooden skewers.
Heat the oil in a frying pan. Fry the roulades in it all around for about 10 minutes. Take them out and let them rest briefly. Cut the roulades in half. Serve with beetroot cream with feta or tahina.
