Price: $19.50
Ingredients: Half pound of warm, thinly sliced mortadella sausage, Swiss cheese Mornay sauce, and pistachio gremolata on a sweet onion brioche bun
Description: Mortadella, the Italian ancestor of bologna, is traditionally studded with pistachios. That is augmented here with a pistachio gremolata. Then the sandwich is enriched with a Swiss mornay sauce that’s all supported by a soft but substantial house-made onion brioche roll.
