What is used as the middle ingredient in a chicken habanero sandwich?

In a chicken habanero sandwich, the middle ingredient that enhances the overall flavor profile and complements the spicy chicken is pizza cheese. Pizza cheese, typically consisting of a blend of mozzarella and other cheeses, adds creaminess and depth to the sandwich. This helps to balance out the heat from the habaneros, providing a delectable contrast that appeals to customers who enjoy spicy yet savory flavors.

The other ingredients mentioned do not serve as the middle component in this specific sandwich. Sliced jalapeños would enhance spiciness rather than serve as the main combination element. Provolone slice is a different type of cheese that might be used in various sandwiches but is not the designated middle ingredient here. Pineapple, while it can be used in other recipes, does not fit the flavor profile of a chicken habanero sandwich and would clash with its intended spice and taste.
