Heat the grill to medium-high. Spread 1-2 TBS of olive oil on both sides of the dough. Stretch into a pie shape and lay on top of the grill grates, sprinkle with a bit of salt, and close the lid. Let cook for 3-5 minutes. Using tongs or a fork, flip the flatbread. Add sauce and toppings as suggested above, close the lid, and let cook 10 minutes more. Remove from the grill, let cool for a couple of minutes, and serve.
