Preheat your oven to 400°F.
Spread ¼ cup of marinara sauce on each pita bread.
Sprinkle ¼ cup of shredded mozzarella cheese evenly over the sauce on each pita.
Top each pita with a mix of your chosen veggies, distributing them evenly.
Sprinkle oregano, garlic powder, salt, and pepper over the toppings.
Drizzle a little olive oil over each pizza for added flavor.
Place the pitas on a baking sheet and bake in the preheated oven for 10-12 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let cool for a couple of minutes before slicing.
