United's snack-pack crew-meals LoL. I'm always carrying at least one of those salt-boxes!
Other than that, I subsist on trail-mix, chef-boyardee, and at least one McDonald's cheeseburger happy-meal per day (subsitute apple dippers for fries and chocolate milk for soda)! And if I don't like the toy, I give it to some kid on my next leg LoL
Oh yeah and ditto on two later posts: Clif Bars and Sandwiches. I always pack enough food to get me through day 1...after that it's snacking on the plane and a good dinner and beer at night!
