Heat a small amount of olive oil in a skillet over medium heat, using just enough to lightly coat the bottom.
Place a tortilla in the skillet and sprinkle shredded mozzarella evenly over the entire surface.
Spread a small amount of pizza sauce over one half of the tortilla. Add fresh basil and any other desired toppings to the same side.
Once the cheese has melted, fold the tortilla in half.
Cook for another 1–2 minutes per side, or until golden brown and crisp.
Remove from the pan, cut into 3–4 pieces and serve with extra pizza sauce for dipping.
