Preheat oven to 375 degrees and line a baking sheet or pizza stone with parchment paper.
Add all ingredients for the crust (only 2 tablespoons of butter) into a medium bowl. Using a hand beater, mix ingredients until well combined.
Put the mixture onto the prepared baking sheet and flatten into a circle about 1/4 inch thick. Bake for 30-35 minutes until the top just begins to brown slightly.
While baking the crust, brown the ground sausage topping if using.
Remove the crust from the oven and paint the remaining tablespoon of butter (and optional seasoning) onto the crust. Bake for 5-10 more minutes.
Assembly

Add a layer of sauce to the baked crust. Then you can begin layering your toppings in any order you like.

Bake for an additional 7-10 minutes until cheese is melted.
