What are the best options to eat when stuck with fast-food as only option?

Although we never try to be in this situation, what is best to eat when stuck with only the fast food option? McDonald's Double Quarter Pounder, but only consuming the patties. Wendy's grilled chicken sandwich and again only consuming the meat with a baked potato? Please advise. Thanks, just a curious cop stuck with options on the road and sometimes limited ones on 3rd shift.
