While traveling in the car, I eat Arby's classic roast beef without the bun or anything, and also their potato cakes. When at the destination, I find a restaurant that is willing to accommodate my needs. Also, try to stay in a motel that has a refrigerator and microwave. Can make oatmeal, potato, probably scrambled eggs (though haven't tried those in microwave yet). It usually isn't too difficult to have a restaurant make you some scrambled eggs and a microwaved potato, or a plain burger, or a plain piece of fish. I have fructose malabsorption and lactose intolerance and can't eat fruit or sweets, dairy, or wheat.
