Road trip lunch ideas

We are going on a road trip this weekend and I want to pack lunch to avoid having to stop to get food. We are leaving very early in the morning and because I prefer to sleep as much as I can, I want to make the lunch the night before and store it in the fridge and just pick it up the morning of all ready to go. I’m thinking about making sandwiches (since it’s the easiest) but I want more food ideas. Also, sandwich ideas that hold good in the fridge overnight is also appreciated!! Like what kind of bread is best, condiments, etc
