I just bring cans of unsalted fish in water or their own juices and sacks of unsalted organic nuts when I go on trips. Run into a grocery store or farm stand to grab fresh fruits and vegetables whenever you see one and eat the stuff raw. You don't need to cook to eat healthily. Even when I'm not traveling most of my diet doesn't involve cooking at all. Just rinsing off dirty vegetables and slicing/peeling is the majority of preparation performed.
