Jay,
I just realized you are in Idaho: Bear Country in Spring and
Fall. So, be aware when cooking, and also when the survival
event is over and you are packing or unpacking. Bears can smell
those food wrappers. Maybe my suggestion (packets of honey and
jam) are not such a good idea. Sugar only, might be better.

You may be at higher altitudes than you are used to; indigestion
nausea etc. could be a problem. Foods that are too spicy or too
fatty make it even worse. So for a Spam type foods, eat slowly,
with liquids; save some for later. Or mix small amount of Spam
with Asian instant noodle package. In the pasta section, I have
seen some very small diameter Italian noodles.

Why not try ordinary super market cookies?
