Leftovers are the food that remains after a meal has been served. They can come from a variety of dishes, such as pasta, casseroles, or roasted chicken. Many people save leftovers to enjoy later, which helps reduce food waste and saves money. They can be stored in the refrigerator or freezer, making them convenient for busy days. Reheating leftovers is a simple way to enjoy a meal again. You can use a microwave, oven, or stovetop to warm them up. Some people even get creative by transforming leftovers into new dishes, like turning grilled vegetables into a tasty soup or stir-fry.
