Although the exact origin is constantly debated upon, it is safe to agree that LA is the birth place of the French Dip sandwich. This hot sandwich, consisting typically of thinly sliced roast beef between a baguette, is known for being served au jus. The juice from cooking the beef is served along with the sandwich as a dip. The beef is often substituted with roast pork, leg of lamb, turkey or ham and served with the natural gravy of the roasts. Sometimes, Swiss, American, Monterey Jack or Blue cheese may be added to the mix. Enjoy this iconic sandwich with a side of pickled eggs, hot yellow chili peppers, tangy coleslaw, or homemade potato and macaroni salads.
