You lost me at "Mountain House." I'd be just as good eating the desiccant packets as the "food" in those.

Packit Gourmet, home rolled meals ala trail cooking.com, and stuff from the grocery store work better - more calories, more nutrition, shorter shelf life - but do you honestly want something in your stomach that has a shelf life of ten years?

Repackaging things into ziplocs and rolling all the air out before sealing does the trick.
