1. Fire up your Ooni pizza oven.
2. Add a dash of oil to your Cast Iron Pan, then add your chicken.
Season with salt and pepper, and place the pan inside your Ooni oven while it heats up. Once the chicken starts to turn golden brown and is cooked through, remove the pan from the heat and set aside to cool.
3. Using a small amount of flour, dust your Ooni pizza peel.
Using a small amount of flour, dust your Ooni pizza peel. Stretch the pizza dough ball out and lay it flat on your peel. Using a large spoon or ladle, spread the pizza sauce evenly across the base. Top with the sliced mushrooms, then the mozzarella. Add a few dollops of pesto, then add your chicken.
4. Slide the pizza off the peel and into your Ooni pizza oven, making sure to rotate the pizza regularly.
5. Once cooked, remove the pizza from the oven.
Sprinkle some torn fresh basil leaves and season to taste. Serve immediately!
