OK, I guess I have some more criteria:

1. Not so high-fat (peanut butter, nuts, and sausages are killers)--I think I'll be gaining about ten pounds on this trip as it is, with no exercise time and a lot of big carb- and alcohol-loaded meals.

2. No preparation required (the muesli sounds great, but I won't have access to the milk, a bowl, a spoon, etc.)

So far trail mix appears to be winning. I might just take a spin around my local Whole Foods clone to see what I can cobble together. I'll look for the sausages--where in the store do they live, richard?
