This recipe is a great way to use up sourdough discard
Place flour, sugar, yeast and salt in food processor bowl. Pulse until combined.
Add sourdough starter to bowl. Place cover on food processor.
With food processor running, add water and olive oil. Process until dough comes together.
Remove dough and place in a lightly oiled bowl. Sprinkle with a little flour and cover with clean kitchen towel or plastic wrap.
Let dough sit at room temperature and rise for 1 hour.
Divide dough in half and cover with clean paper towel or plastic wrap. Let dough rise another 10 minutes.
Preheat oven to 450 degrees.
Place half of dough on lightly oiled baking sheet. Repeat with other half or store in refrigerator for later use. Alternatively, for deep dish pizza, oil a cast iron skillet and place half of dough in skillet.
Using fingers, press dough into desired shape. If using cast iron skillet, press dough to edges. Flip dough to coat other side with oil. Cover with clean paper towel or plastic wrap. Let rest for 1 hour.
Using fingers, gently press dough down and let sit while preparing toppings.
Sprinkle parmesan cheese on top of dough. Sprinkle shredded mozzarella cheese on top. Distribute your favorite toppings on top. Dollop some marinara or pizza sauce on top. Drizzle with some extra virgin olive oil.
Sprinkle parmesan cheese on top of dough. Place slices of fresh mozzarella cheese on top. Place slices of fresh tomato on top of mozzarella cheese slices. Dollop pesto around mozzarella pieces. Drizzle with some extra virgin olive oil.
Place pizza on bottom rack of oven. If making two pizzas, place on on bottom rack, and the other on the top rack. Bake for 18 minutes. Switch pizza positions, moving the bottom pizza to the top rack and the top pizza to the bottom rack. Bake another 7 minutes until bottom is crusty and top is bubbly and melted.

This recipe is flexible. Sourdough starter is equal parts (by weight) water and flour. Generally, I reduce the amount of water in the recipe by the amount of water in the sourdough discard I'm using.
