I to travel a lot with my work. I make sure to prepare my lunch the night before (failing to plan is planning to fail). Like Jannie said, hard boiled eggs are a standard, as are LC finger foods that I can eat as I drive.

Pieces of roast beef, chicken, pork or ham, dry salami, slices of cheese, cucumber slices, celery sticks, lettuce, sliced mushrooms, pizza quiche and that infallible baggie of pork rinds. I'll occasionally whip up some ham or egg salad if I know I can eat my lunch when I'm not driving, or leftovers from supper the night before.

Invest in one of those cooler/lunchbags to keep food fresh and safe to eat. I always take 2 - 1 Litre bottles of water with me too, so I know that I'll always have enough. I also keep a baggie of beef jerky in my briefcase for snack emergencies or if I'm running behind schedule and can't get to supper on time. Hope this helped!
