MRE

The Meal, Ready-to-Eat — commonly known as the MRE — are self-contained, individual field ration in lightweight packaging purchased by the United States military for its service members for use in combat or other field conditions where organized food facilities are not available.

In camping the term MRE is often used to cover any freeze dried, dehydrated, or pre-cooked meal. True military MREs can also sometimes be purchased at surplus for camping.
