Preheat your oven to 400F and position your oven rack in the lower 1/3 of the oven.
Meanwhile, line two baking sheets with parchment paper and place 3 pitas in each baking sheet.
Spread 3-4 tablespoons pizza sauce onto each pita, top with toppings and cheese.
Bake one tray at a time, 7 minutes, until cheese is bubbly and melted.
Store leftover pita pizzas in the fridge. 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.
