I hope I don't start another veggie war with this...

What foods do you use for long-term camping?  Something that requires
minimum refrigeration yet is reasonably healthy?

Obviously I can't keep meet just cool for a week and still expect it not to
kill me.  Donuts are out of the question.  Milk does not keep for long.

Beef jerky?
Smoked fish?
Tortilla bread?
Cheese?
