The chip butty was originally considered a working-class meal and was served in pubs. In the United Kingdom, chips are rarely ever cooked solely for the reason of a chip sandwich. Usually a meal is served with a round of bread so diners can assemble their own chip butty with leftover chips. The chip butty can be vegetarian-friendly if the chips are not fried in lard or dripping, as used to be traditional in a British chip shop.
