I'd love to be stuck in a SHTF situation with a lovely amazon goddess who runs triathlons but I know I better prepare to be stuck with mum who has both kidney failure and CHF. So Mayday food rations and no high potassium treats for my survival pack.
I think the keyword was "survival" in the original question. Granola Bars, great snacks but I would not want to live on them ... though I could use another box of them to snack on. :o
