I just learned about a company that makes pre-packed snacks and meals that require no refrigeration and have a shelf-life of up to two years. The company is GoPicnic. They started out making meal packages for the airline industry. Now, before you say "Ugh, airline food!" GoPicnic's products sound really good. I think I may have had one or two of their snack packs before on flights, or at least something similar, and they were quite tasty.
I wouldn't suggest buying enough of these GoPicnic meals to feed the whole family for a week, but a few of them would add variety to the canned tuna and peanut butter that are staples in a post-storm blackout. You could open one and let each member of the family choose something or give everyone a box of their own to open.
If you're lucky enough not to use these during hurricane season, they make great snacks or lunches for school or work. Buy a few more going into the next season.
The important thing, as always, is to have enough provisions to feed your family for at least three days. After that, maybe the National Guard and Red Cross will be passing out MREs somewhere or major stores will be re-opening.
