Preheat your oven to 400 degrees. Prepare a rimmed baking sheet with tinfoil and cooking spray. Set aside. In a small bowl, combine mayonnaise, milk and dressing. Refrigerate until ready to serve.
Using a large bowl, and a wooden spoon, mix chicken, cheese and wing sauce. On a lightly floured surface, unroll each pizza dough. Cut each into 16 squares, 4 in each direction.
Place 1 heaping tablespoon of the chicken mixture on to the center of each square. Pull corners together and pinch edges to seal in filling. Place 1 in. apart on your prepared sheet. Brush tops with melted butter. Sprinkle with Parmesan cheese.
Bake 15-17 minutes or until golden brown. Serve with dip. Enjoy!
