Oh, yeah, and add black beans to that recipe I posted above. One can. Feeds two very well.
Some other ideas:
Take a cutting board and a decent knife, and buy root veggies. Potatoes, Sweet potatoes, etc... Onions are a must. Garlic too. Also, bring spice. Hot sauces, two or three types.
Butter is not needed. and you are better off not worrying about the melt. Olive oil.
Mayo packets, btw, make a great cooking oil.
Nuts make a big difference in a stir fry as well.
The best advise I can give for an extended trip is to eat foods similar to what you normally eat. Fifteen days of different food is not fun for anybody.
On my first trip we ate mostly 'camp food.' Lots of trail mix, cereal bars, etc...makes for really crabby people. Most 'travel' and 'camp' foods a pretty high in sugar content, and you DO NOT want the person you are in close contact with to be crabby and pissed off (which sugar does to many people). Lots of veggies is key. Root veggies keep the best, but take some more perishable ones to start you off.
Also, be aware that sea water is pretty cold in the pacific. You can use it to keep things cool. Just keep some kind of container that can seal, and keep your perishable meats in those vacum pack or ziplock bags, stash them in the container, and fill it with sea water. Change the water once it gets warm.
I'm sure there are other things I'm not thinking of now, but that is a few that may be of use to you.
