"Leftover" refers to food that remains uneaten after a meal. It can include various dishes, such as pasta, pizza, or stir-fry, and is often stored in the refrigerator for later consumption. Leftovers can help reduce food waste and save time and money by providing quick meal options. Many people enjoy repurposing leftovers into new meals, such as turning roast chicken into chicken salad or using vegetable scraps in soups. Proper storage in airtight containers can help maintain freshness and prevent spoilage, making leftovers a practical choice for busy lifestyles.
