Thanks for everyone's replies. I always have water with me, and when I go to AZ I actually fill enough bottles to last me a full day bc I hate buying water. I refill them all at the hotel before I leave the next morning. So on that long trip I am drinking 80 oz of water a day (my minimum daily goal) plus usually juice and yes, often a bottle of pop, plus more water once I'm off the road.
This last trip out there I tried cutting up deli turkey and cheese to eat on crackers, but I realized as I was cutting it all up I wouldn't be able to eat it while I was driving. It did make a nice meal at the hotel that night though, since I was too tired to find anywhere for supper.
I do take granola bars, had forgotten about that. Jerky and nuts could work, and string cheese. I wish there was a way to keep apples fresh after cutting them. Bc of a filling btwn my two front teeth that has fallen out multiple times my dentist told me to never bite off apples or raw carrots, stuff like that. I never thought of microwave popcorn for hotel snacks. Much better choice than a late-night vending machine visit!
We don't stop to eat when we're on the road. It's grab smthg and back in the car to keep driving. I would love to find smthg portable that actually feels like a meal and fills me up, and that I can eat while I'm driving. That's one reason I get pizza at gas stations. It checks all those boxes.
I really appreciate everyone's ideas. I have some time before I'll travel again so I'll hopefully have smthg figured out before then!
