Melt the butter in a saucepan over medium heat.

Add the flour and whisk until fully combined and the mixture takes on a slightly nutty smell, about 1-2 minutes. Slowly pour in the milk, whisking constantly until incorporated.

Continue whisking for 2-3 minutes, until the mixture comes to a boil and begins to thicken.

Add in the dry mustard, nutmeg and pepper.

Remove from the heat and stir in the cheese, whisking until fully combined. Allow to cool slightly.

Preheat the oven to 400 degrees. Spray a pizza sheet with non-stick and roll out the pizza dough onto the sheet, making sure to create a crust high enough to hold in the cheese sauce.

Drizzle the olive oil on top of the dough and brush to coat. Sprinkle with the garlic powder.

Prick the pizza dough with a fork on the crusts and center to stop it from rising too much. Place in the preheated oven and bake for 8-10 minutes or until lightly golden.

Remove the dough from the oven and begin assembling the pizza.

Spread the cheese sauce over the pizza (you will likely have extra), followed by the shredded mozzarella cheese.

Tear up the slices of turkey and arrange them over the pizza. Repeat with the crumbled bacon and finally the tomato slices. Sprinkle Parmesan cheese on top.

Bake for an additional 10-12 minutes or until the cheesy is bubbly and melted.

Remove from the oven and allow to cool for 5 minutes. Sprinkle chopped parsley on top, slice pizza and serve.
