Are fine bread crumbs mixed with Tuna Salad in sub shops?

It's not a common practice for sub shops to mix fine bread crumbs into tuna salad.

Here's why:

* Texture: Bread crumbs would add a crunchy texture to the tuna salad, which might not be what customers are looking for in a sub.

* Moisture: Bread crumbs can absorb moisture from the tuna salad, making it drier and less flavorful.

* Tradition: Tuna salad in sub shops is usually made with a classic combination of tuna, mayonnaise, onion, and sometimes celery. Adding bread crumbs would be a significant departure from the traditional recipe.

However:

* Some people might choose to add bread crumbs to their tuna salad at home for personal preference.

* Some sub shops might have a special tuna salad recipe that includes bread crumbs, but this is uncommon.

Ultimately, the decision of whether or not to include bread crumbs in tuna salad is up to the individual or the shop's specific recipe.
