In a small cooler between the front seats of my vehicle you'll find individual zip top bags of:
- Cheese cubes
- Meat snacks, or possibly crackers
I find these three foods to be the best snack for between meals. They're easily accessible and reachable while driving or co-piloting, and hit all the major needs. Each item is snack size so there's no (or little!) guilt for repeat consumption, and you get the sugar, salty, protein-y goodness along with a little silky texture from the cheese. No one wants to be in the car with an upset tummy or the feeling of regret that usually follows fast food, and these snacks keep well and will always satisfy, even if your hotel is void of desirable food when you stop for the night.
