Which cheese is used in the preparation of the Speciality Chicken?

Feta cheese is the correct choice for the preparation of the Speciality Chicken. This cheese is known for its tangy flavor and crumbly texture, which enhances the overall taste profile of the dish. The use of feta adds a unique Mediterranean flair, complementing the other ingredients of the Speciality Chicken, such as the grilled chicken and various toppings that aim to create a rich and bold flavor experience.

Cheddar, Swiss, and provolone cheeses, while popular in many other dishes, do not provide the same distinctive taste that complements the specific components of the Speciality Chicken. They are often used in other pizza offerings or sauces but are not aligned with the intended flavor and texture that feta cheese brings to this particular dish.
