Preheat your oven to 400°F (200°C).
Prepare the filling by combining the mozzarella cheese, pizza sauce, diced bell peppers, sliced olives, oregano, salt, and pepper in a bowl.
Place one tortilla on a clean surface and spoon an even layer of the filling onto one half, leaving the edge clear.
Fold the tortilla over the filling and press down the edges to seal.
Brush both sides of the filled tortilla pockets with olive oil.
Bake the tortilla pockets in the preheated oven for 15-20 minutes or until golden brown.
Remove from the oven and let cool for a few minutes before serving.
