The survival foods offered by the plethora of web sites are a carbohydrate
feast, they center around grains and legumes and are really not what a
paleo dieter would want.  The amount of meat offered is miniscule, and
prohibitively expensive when it may be found.

I suggest lots of dehydrated meat, it can be eaten without cooking while
canned meats usually are not palatable cold, plus, they take a lot of room.
 You can store food for a long time as jerky or pemekin and such.

I have experimented with keeping jerky, if you place it in a Mason jar with
an oxygen absorber, available from many survival sites, and crank down on
the lid, it will keep for quite a long time.  Pemekin keeps for ages,
anyway, as Ray has noted here or on another list, don't remember which.

You can get decent dehydrated vegetables, but they require a lot of water
to cook and there again, you must cook them.

I suppose how you prepare depends on where you live, and how serious you
think the problem is going to be.
