MREs, or Meals Ready-to-Eat, are self-contained, individual meal packages designed for military personnel and emergency situations. They are lightweight, durable, and can be stored for long periods without refrigeration. Each MRE typically includes an entrée, side dish, dessert, and accessories like utensils and napkins. MREs are designed to provide balanced nutrition and are easy to prepare. Most can be eaten cold, but many come with a heating element that allows users to warm the food. They are also used by outdoor enthusiasts and in disaster relief efforts due to their convenience and long shelf life.
