Once upon a time there was a girl whose wicked stepmother forced her to clean the entire house for Pesach all by herself. So while her stepmother and stepsisters left early for the grand seder at the Prince's palace, the girl spent the afternoon sweeping and dusting and washing and polishing. As she finally burned the last crumbs of chametz in the fireplace, she saw the sun setting and knew she would never make it to the Prince's seder on time, so she began to prepare her own meager dinner: a little Passover pizza. But miraculously, her fairy godmother appeared and transformed the pizza into a flying carpet to take her to the palace, and the cheese into a beautiful dress for her to wear. And to commemorate this story, to this very day, that cheese is named after that girl: they called her Matzah-rella.
