afoodieinaustinVerified Diner Dined on Sep 26, 2024Knuckle Sandwich has the best new sandwich in Austin and no one is talking about it. They’re located in South Austin. I highly recommend trying the sandwich called "The Knuckle Sandwich" which is a cold cuts sandwich with mortadella, capicola, and salami. All the ingredients come together perfectly but my favorite part was these crunchy cheesy Parmesan crisps that give an extra texture and crisp to the sandwich.
