Spread the hummus over the pita (or tortilla), except for the edge. Sprinkle with cracked black pepper. Add the baked toppings (these toppings are not baked before they go on the pizza; the name just refers to toppings that get baked on top of the pizza). As a variation, add pizza sauce instead of hummus.
Bake the pita pizza at 350 F for 7 to 8 minutes. Then spread any of the fresh toppings on the pizza after it comes out of the oven.
