This green bean-laced potato salad is hearty enough to serve as an entrée, but you could also pair it with grilled vegetarian sausages for a bigger meal. If you don't have white balsamic vinegar in your pantry, use any mild variety, such as white wine or rice vinegar.
This recipe was a winner in our 2008 Restaurant Poll, and is a popular sandwich at Chicago Diner in Chicago, Illinois. We were impressed by its innovative use of beet and pickle juices to turn seitan into a tangy substitute for corned beef. Can't find beet juice? Purée a 15-ounce can of beets and use it for the marinade.
