Combine warm water, yeast, and sugar in a bowl. Add ½ cup flour and let it sit for 15 minutes until foamy.
Mix in oil, salt, and 2 cups flour. Knead until smooth, adding reserved flour if needed. Rest dough for 10 minutes.
Preheat oven to 500°F (260°C) and place a large skillet inside.
Roll dough into 8 balls, then into ¼-inch thick 8-inch circles, adding flour as needed.
Moving quickly, add enough dough balls to fit on the skillet and bake until puffed and golden (3-5 minutes each).
