I actually travel with a small soft cooler with pre-cooked chicken. An ice pack (gel) keeps the chicken for the entire day. I pack 3 (5 oz) bags of cut up chicken. I cut up peppers and cucumbers as well and pack them. Then I do a couple of bags of almonds as well. This generally does me for trips and the bag is really quite small and fits at the top part of my carry on. I don't do TNT so I also have Kashi cereal (dry) stuffed somewhere as that is always a good food.
