This recipe is great on roast beef sandwiches - hot or cold. It's origin is Al's #1 Italian Beef in Chicago. The recipe was printed in the Blue Plate Specials cookbook. It's like a regular giardiniera, but everything is chopped finely like relish so that it works well on a sandwich. Hint - the food processor is great for mincing the vegetables. Note - the cooking time is really the chill time. This is also excellent with cream cheese on a cracker.
