When we do our road trips, we usually take the following. First we cut up all veggies still in tthe fridge that would otherwise rot while were gone ( Cucumber, carrots, celery ...). We cut them up into sticks, and also bring some of this small individual hummus cups. We also take some granola and cups. When we want it, we just fill up a cup, Its easier and less messy to kinda' sip' granola from a cup while driving, than reaching into the bag and having half of it wind up on the floor. We take cans of corn, olives, chickpeas ( with pull tabs so no need for can opener, even though we take one of those also). Various dried fruits, nuts. Fresh apples, as they usually hold up for days in the car ( as long as not leaving them in a very hot car). Peanut butter and something to dip with ( pretzels, crackers). These are just snack things, but if we're doing a real long trip, and know we may be driving through lunch, well bring some bread , or things to make sandwiches with on the go. I've been doing extensive road trips for decades, so we kinda got it down to a science .
