In a large mixing bowl, dissolve the sugar in warm water. Sprinkle the yeast over the top and let it sit for about 5 to 10 minutes, until frothy.
Add the flour, olive oil, and salt to the yeast mixture. Mix until a dough forms. Turn the dough out onto a floured surface and knead until smooth and elastic, about 5 minutes.
Place the dough in a greased bowl, turning once to grease the top. Cover with a clean cloth and let it rise in a warm place until doubled in size, about 1 hour.
