Combine warm water, sugar, and active dry yeast. Let it sit for 5 minutes until the yeast becomes frothy. In a separate bowl, mix the flour and salt. Create a well in the center and pour in the yeast mixture and olive oil. Stir until a shaggy dough forms. Transfer the dough to a floured surface and knead for 5-7 minutes until it becomes smooth. Place the dough in a greased bowl, cover it with a kitchen towel, and let it rise for 1-2 hours or until doubled in size.
