Position the top two oven racks towards the middle and lower of the oven. This is so you can bake 6 pitas at once in two pans. Preheat the oven to 400F.
Line two baking sheets with parchment paper.
Load up the pitas:
Spread approximately ¼ cup pizza sauce on each pita. Distribute the toppings on top of the pitas and sprinkle the mozzarella cheese on top.
Bake:
Bake the pita pizzas for 7 to 8 minutes, switching tray positions halfway through. You can also bake them one at a time, of course. Once the cheese is bubbly and golden on top, remove the baking sheets from the oven and serve.
Store:
Leftover pita pizza can be stored in the fridge for up to 2 days in an airtight container or zip bag. It can be reheated in the oven at 350F for 5 minutes, in the toaster oven through a light-medium toast cycle, in the air fryer at 340F for 6 minutes, or in the microwave for 45 seconds (this is the least recommended method).
Notes
To pack for school lunch, lightly toast in the toaster oven (or in your oven's broiler on low), remove and cool down to room temperature before packing in a lunchbox.
