The term 'Pizza Pieces' refers to two items that are commonly associated with pizza: Zees (4 letters) and SLICES (6 letters). Zees are the individual pieces of a pizza that have been cut into small, triangular shapes. SLICES are larger portions of pizza that have been cut into rectangular or square shapes. Both Zees and SLICES are popular ways to enjoy pizza, and they can be served as part of a meal or as a snack.
