In my book, fast food is not the best way to get your meal but sometimes it's just unavoidable. Packing sandwiches and fruit for a long road trip or a lengthy flight isn't always practical or appealing. With the holiday road trips on the horizon, it's best to be prepared to make the healthiest choices possible when a drive-thru or airport quickie is the only option. I looked at five popular fast food joints and picked one 300 calorie meal from each menu. Come take a gander and tell me which one fits your appetite best.
