Pemmican! Make your own (http://www.dannyroddy.com/main/2009/5/10/upping-production-or-how-i-have-become-a-one-man-pemmican-fa.html), or buy some from US Wellness Meats. I recently saw some Banff Film Festival films and was sorta shocked by the "foods" brought along on expeditions. Massive amounts of time and fuel spent to make substandard processed foods, when a month long pemmican powered expedition would be EZ.

You could make a coconut pemmican-like substance with taking shredded coconut and mixing it into either butter or coconut oil.

For protein, I'd see if you can make your own beef jerky, and go light on the salt.

You could also mix up some whey protein and coconut oil, to get a stable protein source.

If you've got a hard container, you could bring boiled eggs along. As long as the shell isn't cracked they keep for two to three weeks.

The only problem is that I see all of this stuff getting a little boring after two or so days.

When I go on climbing trips I like to pack a mix of toasted unsweetened coconut, walnuts and raisins. Makes a great tasty snack :)

I use this type of coconut and toast it myself in a frying pan: http://www.amazon.com/Bobs-Red-Mill-Unsweetened-Shredded/dp/B000ED9LIU#sf

When I travel I always take coconut oil "cookies", canned sardines, cooked hamburgers or hotdogs, cheese slices, hard boiled eggs, some nuts... can last a couple of days

Make your own 10 dollar Jerky maker offered by Lex Rooker.

The jerky will last your two weeks.

Anything raw vegan. Fruit, nuts, seeds, salad greens, etc.

EDIT: That wouldn't cover everything, but at least it would be a start.

I always suggest the same thing to similar questions, something I heard in an early Robb Wolf podcast, and that is to melt coconut oil and pour it into a jar of nuts and dried fruits (and whatever else you want) and let it solidify in there and you can just spoon it out when you want it. very calorically dense snak

I soak and dehydrate nuts, almonds, walnut, pecans, brazils, etc. Soaking makes them easier to digest. I also make my own jerky - simple enough - tamari, pepper, garlic powder and ginger powder. Go easy on the tamari, it can get salty. My jerky lasts a very long time, months for sure, but I usually eat it within 3 months so I don't know the actual shelf life. Then there is pemmican. Made properly it lasts indefinitely. I made mine in the traditional native American style, just tallow and dried meat, no berries. Adding berries will cause the pemmican to spoil. It would need to be consumed more quickly. But adding berries will also make it more palatable.

I hope this helps!

I love the little packets of Justin's nut butter. They transport really well and won't go bad if you don't use them. You can find them at Whole Foods and some Target's here, but I don't know if they are availabe where you are at.

My favorite on the go food is my own trail mix of unsweetenened coconut flakes, any raw nuts I have on hand, unsweetened dried cranberries and either dark chocolate chips or unsweetened carob chips. It really calms a rumbly tummy for awhile!

Smoked salmon or trout. Smoked eggs, tuna poached in extra virgin olive oil. Jerky. Almonds, pistachios. Plantain chips fried in red palm oil. avocados.
