I use coucous a lot:
1) Put couscous in a pan, boil water in 2nd pan, pour water onto couscous, put lid on and leave 5 mins;
2) Meanwhile heat up your sauce of choice in the pan you used to boil water in - should get it at least warm in 5 mins;
3) Mix and eat.
I am trying to make an edible high-energy sauce that has roasted nuts, chicken livers, kidney beans, chickpeas, toms, chocolate, onions etc etc but no success yet (tyring to make a simple Mexican mole). The idea is to make the sauce before the trip, reduce as much as possbile and then pack it into little containers. BTW sun-dried toms are a good meat substitute, they taste great...
Am also working on rye bread with raisins in, it is great trail bread, lots of energy, tastes great and does not get squished in the pack/panniers.
