Well, depends. It kinda looks like a regular wrapped sandwich to me, except it comes in a can. So if the can is something that keeps for a week or something, I'd try it. If it keeps forever though, well, I don't want to imagine what they'd put in the bread to make it last so long, so I'd have to pass.
"CandwichTM tastes great, and because of the specially formulated healthy 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)!"
