Combine Dijon mustard, red wine vinegar, salt, pepper, and Pecorino Romano or Parmesan cheese in a mixing bowl.

Once everything is combined, cut the Italian salami into strips.

Ashmore then adds the garbanzo beans, chopped iceberg lettuce, shredded mozzarella cheese, and salami to the dressing before mixing everything together.

Shake the salad well.

To add even more flavor, mix in some extra Pecorino Romano or Parmesan cheese, as well as some pepper, before serving.
