1. In a mixing bowl, combine warm water, sugar, and yeast. Let it sit for 5 minutes until it becomes frothy.
2. Add flour, olive oil, and salt to the yeast mixture. Stir until a dough forms.
3. Knead the dough on a floured surface for about 5-7 minutes until smooth and elastic.
4. Place the dough in a lightly oiled bowl, cover with a damp cloth, and let it rise in a warm place for about 1 hour or until doubled in size.
5. Punch down the dough and divide it into 4 equal parts. Roll each part into a ball and let rest for 10 minutes before shaping into pizzas or calzones.
