Which sandwich features tuna salad combined with cheese?

The sandwich that features tuna salad combined with cheese is known as a tuna melt. This classic dish typically consists of a tuna salad, which is made with canned tuna mixed with mayonnaise, celery, and seasonings, then topped with cheese—often cheddar—and heated until the cheese is melted and bubbly. The combination of the savory tuna salad with melted cheese creates a comforting and flavorful sandwich.

In contrast, the tuna croissant generally utilizes a flaky croissant as the base for the tuna salad but does not specifically incorporate cheese. The steak torta is a different type of sandwich that centers around steak and various toppings, while the guava BBQ pork sandwich consists of pulled pork with guava BBQ sauce, neither of which involve tuna salad or cheese. Therefore, the tuna melt is the distinctive choice that features both elements effectively.
