Even rice, beans, and potatoes can cause nasty foodborne illnesses if stored at temps of greater than 40 degrees for just a few hours.  Doesn't happen often, but it is not a chance I'm willing to take.  I've had food poisoning on a canoe trip (from a pre-trip pizza) and that's an experience I don't care to repeat...ever!

I swear, Old_Salt constantly suggest saving leftovers when we trip together just because he like to watch my skin crawl when he says it.

I like eating the Vigo dishes too.  When I solo, I just divide the package in half so I cook only what I can eat.
