It kinda depends on what sort of amenities you'll have. Will you have access to a kitchen? Microwave? Do you need to come up with hot meals everyday, 3 times a day? Or just one meal to take on the road while driving to your destination? Does your car have an outlet so you can plug in an appliance while you're driving? Or do you have to make your food at your home and try to figure out a way to keep it warm while traveling? I guess I would bring a small microwave and pack a cooler with meals you've already prepared ahead of time, then just heat up the food in the microwave as needed and eat. I'm curious to see what other suggestions you get!
