I wondered about that YC comment also. Home dehydrated spaghetti with sauce turns out pretty good. I guess he means the vile stuff like canned chef boyardee. One of the Adirondack Lean2rescue guys I work with opens a can of the stuff and eats it cold for dinner. gag.
I still chuckle about a lean2rescue trip where one of the guys was eating out of can with no label. We asked what it was and he said, " I dunno, it was on the shelf of the lean-to when we got here".
