Follow Glenda's Sourdough Pizza Crust recipe. I love to make up a batch of 5 or 6 and freeze them before they ferment. I take them out of the freezer the night before I need it. It thaws and ferments while I am sleeping and throughout the day at work. I love this the best in a big pizza pan so I can get the crust as thin as possible. Proof for 1-2 hours on the pizza pan.
If you like, you can also par bake the crust at 450 for 5 minutes before applying toppings.
Pre-Heat oven to 450 when you are ready to bake
On the prepared crust, spread approximately half of the alfredo sauce recipe over the crust.
Shred and spread the chicken breast across the top of the pizza (You can use baked chicken breast for this if you like, I was short on time!)
Spread quartered cherry tomatoes across the pizza
Add sliced mushrooms if desired
Sprinkle the remaining 6 tsp of parmesan over the top of the pizza
Bake for 10-15 minutes, checking frequently so it does not burn.
