In a small bowl, combine the warm water, sugar, and yeast. Let it sit for about 5-10 minutes, or until it becomes frothy.
In a large mixing bowl, combine the flour and salt. Make a well in the center and add the yeast mixture and olive oil. Mix until a dough forms.
Knead the dough on a floured surface for about 5 minutes until smooth and elastic. Place the dough in a lightly greased bowl, cover with a clean kitchen towel, and let it rise in a warm place for about 30-60 minutes, or until doubled in size.
