Well for 10 miles you don't need to eat anything as far as keeping up your energy goes.
If you're hungry and it's a problem, eat something and eat that many calories less at other times in the day. For instance, if you eat a banana as a snack on the drive home, then eat 100 calories less for breakfast or 50 calories less for diner and lunch.

Personally I find something like an apple or a banana decently filling, but it'll only last for like 20 mins. If you want to eat bananas, I suggest eating them pretty green, those are harder to eat because they're not ripe and sit longer in the stomach than when they get nice and yellow/brown. I've also found that eating an entire apple as fast as you can fills you up for a couple mins. I'd stay away from any energy / granola bars or nuts as those won't fill you at all unless you eat like 900 calories of them. Same goes for any sandwich / bread / meat. All terrible low calorie filling snacks.

If you can stomach raw vegetables, eat those. Broccoli, cauliflower, radishes, carrots, celery -- all stuff that's hard to eat, fills you up and has almost no calories. If you're really hardcore you'll eat an onion.
