Man, that is hard yards. If that is the case, gotta recommend that you get a hold of various herbs and spices / condiments and use them with things like rice (even the dehydrated verison) and spuds to make up various curries and hashes. The "PMWU" cookbook (and old one that most grannies have on their shelves, but still available in reprint) has various recipes dating way back (depression etc) that can help out with this sort of stuff.
Good luck
PS, buy some quick eze / anatacid as well, from personal experience, a few weeks on tinned rats and you will be feeling quite ordinary.
