The One-Week MRE Food Supply provides three entrées a day, delicious side dishes, snacks, desserts, drinks, and more for 7 days. Having a supply of MREs is a great way to eat superb, pre-cooked meals when you’re camping, during an emergency, or when there just isn’t time to cook tonight’s dinner. Stored in metalized pouches, they warm up quickly and easily open to enjoy. The on-the-go convenience of MREs makes them ideal for any emergency kit. You can also rotate these MRE meals into your camping, backpacking, or everyday meal planning.
