Which sandwich includes ham and dijon as ingredients?

The Billy Club sandwich features ham and dijon as key ingredients, making it the correct answer. Specifically, the Billy Club is unique because it combines layers of roast beef, turkey, ham, and cheese along with dijon mustard, which contributes to its distinctive flavor. The use of ham along with dijon mustard complements the other meats and helps to create a balanced taste profile that is savory and slightly tangy. This combination is central to what makes the Billy Club a popular choice among customers.

In contrast, the other options do not include both ham and dijon. The Italian Night Club typically includes salami, capicola, and other Italian meats. The Totally Tuna sandwich is primarily based on tuna salad and does not feature ham or dijon. The Vito sandwich, which is an Italian sub, includes layers of meats like genoa salami and provolone but again does not incorporate ham and dijon mustard. This distinction highlights why the Billy Club is the only correct choice when looking for a sandwich containing those specific ingredients.
