I am forced to commute 40 miles for every day for work and so I end up eating a lot of meals on the road. This is certainly not my favorite habit but it's just a fact of the matter and so I'm dealing with it in the best way I can, which is to try to find the least evil food that's available to me. I've compiled a list of cheap, partially healthy foods that can be found on nearly any road trip in the US. I say partially or semi healthy because this is really just going for less of the bad things like sodium and fat and doesn't really address adding nutrition.

While most being a little high in sodium, these things are better options than most if you're on the road and need a bite. The real killers are french fries, soda and mayonnaise so if you can exercise some self-control, make sure to just do water as the drink and try to either hold the side or go easy on the fries (try a small).
