Mr. E
n.— «On combat duty, American soldiers are fed on MREs, or Meals, Ready-to-Eat. These are virtually indestructible and long-lasting packed meals of up to 1,300 calories each. Of course, as with all institutional food, MREs are not loved. “Meals, Rarely Edible,” some soldiers call them. “Mr E” (mystery) is another nickname.» —“You can’t fight on an empty stomach” by Rrishi Raote Business Standard (India) July 17, 2007.
