Preheat oven to 350 degrees F. Mist a 20 wells of a mini muffin tin with nonstick cooking spray and set aside.
Combine all ingredients in a medium bowl until well-combined. Using a spoon, fill each muffin well about three-fourths full.
Bake for 25-30 minutes or until tops are golden. Allow to cool for 5 minutes. Run a sharp paring knife around the outside of each pizza bite and gently remove from mini muffin tin. Serve hot with pizza sauce, if desired.
