In a small bowl mix chicken cubes with Buffalo sauce and set aside.
Spread Alfredo sauce on prepared pizza crust and top with 1/2 the mozzarella cheese. Top with chicken cubes (sprinkle on any sauce remaining in the bowl), onions, mushrooms, black olives and cilantro. Finish with the rest of the cheese.
Bake at 425 for about 15 minutes or until crust is brown.
