Roll out pizza dough according to directions on package (mine was on a 15x10x1" baking sheet) and cook for about 5 minutes at 375 degrees (if the directions differ on your pizza dough packaging, follow those directions instead).
Take pizza dough out of oven and spread Alfredo sauce over the entire top of dough. Sprinkle cheese, toppings, and chicken over the top of the sauce.
Brush some olive oil (a used not quite a tablespoon) around the crust edges and sprinkle with Parmesan cheese and garlic salt (I also sprinkled the entire pizza with a little bit of Parmesan cheese and garlic salt).
Put pizza in oven and bake for another 10 minutes (or until cheese is melted and crust is done).
