Pocari Sweat tastes quite good, you find it in most vending machines in Japan. My favourite is the Jamaican soup mix at my local Tesco called Cock Soup. The packaging used to say that it was "just like daddy's" but they changed it.
I haven't seen canned bacon but that's likely because I haven't looked for it. That'll have to change now that you've brought it to my attention. I have seen various freeze dried meats (beef and pork) and they've all been better than I expected.
