What to eat on-the-go between jobs??

Options
Hello,
I work two jobs: one full-time desk job and one retail part-time.. my biggest problems is nights I work both jobs, i don't have time to come home and eat first and any meal I have needs to be able to be eaten in the car or in less than 10 min on my break around 8:30pm, which I feel is a little late to be eating. I usually have brkfst around 7-7:30am.. eat lunch anywhere between Noon - 2pm.. and "dinner" at 5:30-6pm..and it's either a sandwich that doesn't really make me feel full or it's fast food (which also tends to be less than satisfying), both being eaten in my car on the way to my night job. If i don't eat on my way, then i'm slamming a soda, chips, candy and other crap at 8:30pm on my break or eating a lunchable at 11:00 pm on my way home.

I'm hoping to find some good suggestions on a on-the-go meal and/or snack that will help make me feel full and satisfied until breakfast.. a lot to ask I know.
