Fuel for climbing

We have settled on cheese and salami as the perfect sandwich filler. They remain tasty in the cold, don't freeze easily, and restore energy like nothing else I know.

We have been averaging 2 each a day, plus a couple of Norwegian High Energy chocolate bars. That means that in this photo Nick is eating his 20th+ cheese and salami sandwich of the trip so far. He doesn't seem to be losing his appetite for them.
