MRE

The MRE is a consumable item in the Fallout: New Vegas add-on Lonesome Road.

Characteristics
A military ration found extensively in the area surrounding the Divide. The MRE contains boneless pork chop as the main course along with standard sundries. This food item is one of the few radiation free foods in the game, and its nutritional value in hardcore mode is amongst the highest found in any food, on par with the much heavier caravan lunch.

The MRE provides relatively low HP restoration in hardcore mode, given its high nutritional value. Notably, however, its HP regeneration is significantly better when used outside of hardcore mode, presumably to compensate for its lack of utility in sating hunger. Food items don't typically work this way.

Locations
This is a list of fixed non-random places where you can find MRE.

At the Canyon Wreckage. On the left, there is a wooden board that says "Lonesome Road". In the duffle bag below this, there is a MRE.

If you leave Ulysses alive in the final mission, he will be at the entrance to canyon wreckage. You can ask him if he has recovered anything from the dust of Hopeville which will result in 4 MREs, amongst other minor loot.

Behind the Scenes
MRE stands for "Meal, Ready-to-Eat" and is the self contained individual field ration used by the United States military.
