Grease the Sheet Pan with oil and sprinkle with cornmeal.
Combine the pizza dough ingredients in a large bowl. (The mixture will look dry.) Turn the dough out onto a lightly floured surface and knead for 4 minutes. Sprinkle with additional flour as needed to prevent sticking.
Roll the dough into a 12" (30-cm) circle, adding flour as needed, and transfer to the prepared Sheet Pan.
Set the Deluxe Air Fryer & Oven to PIZZA. Adjust the time to 15 minutes.
Mix the sauce ingredients together and spread it on top of the pizza dough.
Top the pizza with the spinach and red peppers. Sprinkle the mozzarella over the toppings.
When the display says, “Add Food,” place the Sheet Pan in the oven (on the Wire Rack) and press START.
Remove the pizza from the oven and transfer to a cutting board. Cut the pizza into 8 wedges and serve.
