Interstate food

What do the meatless eat when traveling by interstate? If they have two young children and a dog along for the ride, and 10 hours of I-20 stretching ahead, it's an uninspired combination of fast-food salads and bean burritos. In a pinch it might be an order of fries and a milkshake. Or it might be a "veggie" plate like this gem I had at, well, Cracker Barrel. It's good to be home. Very, very good. 20130120-193943.jpg
