The lamb sandwich, lamb 1.3. (all of the sandwiches at Snack are named in this way, by meat or method of cooking and a number.) Juicy pieces of braised lamb are served on ciabatta with roasted red onions, tomatoes, arugula and a homemade roasted tomato aioli sauce. The lamb and tomato aioli are like lost lovers reunited at last, while the rest of the flavors do their parts in supporting roles so that all work in unison to create a succulent sandwich. Did I just say succulent sandwich?! Well, it is!
