This is the ultimate comfort food that involves those ingredients always lurking in your cupboard: potatoes, cheese, and flour. Officially known as Llapingacho, all you need to do is cut up potatoes, boil them in salt water until soft, and mash them. The roll the mashed potato, stuff it with cheese, and flatten as patties, before frying in oil until golden brown. A saviour when you are in need of a food shop.
