Why would you buy a Candwich-brand sandwich in a can? Helpfully, the site lists three value propositions: "Healthy fast food," "Great for vending," and, of course, " Disaster preparedness ."

With an extended shelf-life, Candwich™ is ideal for emergency food storage needs in the event of a natural disaster. Candwich™ tastes great, and because of the special Army formulated recipe, the bread stays as soft and sweet after one-year in storage as it did the day it was made (If you can ever keep them around that long)!

It comes in 24-packs, too.
