Lunch on the R-U-N!

Hello everyone, I am a full-time college student that commutes an hour one way. I do not mind eating out every once in a while, but I really do not have the time or the money to do it twice a week. I need some lunch ideas that I can keep in my insulated lunch bag for at least 5 hours without spoiling or tasting awful. I always keep fruit, nuts, and crackers handy. I sometimes take sandwiches or wraps, but they are really getting old, and fast. So I would love to hear what you guys eat on the run!! Thanks ahead of time!!
