A dish of leftovers is a type of meal that consists of food that has been cooked and stored in the refrigerator for later use. It is usually made up of ingredients that have been cooked in advance and then reheated when needed. The term 'HASH' is used to describe a dish of leftovers that has been chopped or diced and then mixed together. This type of dish is often served with potatoes, eggs, or other accompaniments.
