Make the artisan pizza dough or buy your favorite pizza dough
Preheat your oven (with the pizza stone inside, if using) to 450-500 degrees, depending on your ovens highest temperature setting
Add 1 tablespoon of butter into a small sauce pan and place over medium heat
Once the butter has melted, whisk in 1 tablespoon of all purpose flour and cook, whisking continuously, for about 30 seconds
Slowly whisk in 2/3 cup of whole milk
Add 2 pasted cloves of garlic and a pinch of salt and black pepper
Cook over medium heat for another 60 seconds or so, whisking continuously until the sauce begins to thicken a bit
Add 1/3 cup of grated parmesan and remove the sauce pan from the heat
Whisk the sauce until the parmesan has been fully incorporated
Shape the dough into rounds
Divide the white sauce over the pizzas leaving a 3/4 inch boarder for the crust
Top with shredded chicken, shredded mozzarella and shredded parmesan
Brush the crust with melted butter and sprinkle with garlic salt
Carefully transfer the pizza (one at a time) onto the pizza stone or onto a baking sheet and into a 450-500 degree oven and cook until the cheese is melted and the crust is deeply golden brown (about 10 minutes)
Transfer to a heat proof surface and repeat with the second pizza
Slice and enjoy!
