I have done some "go light" over nighters before and found a good menu is Hawiian pizza. Pick up a couple large or extra large Hawaiian pizzas (part as dinner) the night before, re-package into some gallon ziplocks and you're good to go. No muss, no fuss, no stove, fuel, plates,etc. We all know pizza is good cold but Hawaiian packs well, has all the food groups and isn't greasy. Worked quite well and no cleanup required. Seriously, not bad. Slightly less recommended was a trip taken earlier when I packed in route by ordering 21 regular McDonalds cheese burgers to go. Wasn't terrible but they did get old after a dozen or so.
