Which sandwich includes two times the cheese in its ingredients?

The Club Tuna is the sandwich that includes two times the cheese in its ingredients. This sandwich typically features tuna salad, which is mixed with mayonnaise and often combined with two slices of provolone cheese, effectively doubling the cheese amount compared to other standard sandwiches. This extra cheese not only enhances the flavor profile but also contributes to a richer texture, making it a distinct choice among the offerings at Jimmy John's.

In contrast, the other sandwiches listed have standard cheese proportions that do not include as much cheese. Thus, the Club Tuna distinctly stands out with its increased cheese ratio, making it the correct choice for the sandwich that includes two times the cheese.
