1. In a mixing bowl, combine the warm water, yeast, and sugar. Let it sit for about 5 minutes until it becomes frothy.
2. Add the olive oil, flour, and salt to the yeast mixture. Stir until a dough forms.
3. Knead the dough on a floured surface for about 10 minutes until it becomes 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. Preheat your oven to 475°F (245°C).
6. Punch down the dough and divide it into portions for pizzas or calzones. Roll out the dough on a floured surface to your desired thickness.
7. Add your favorite toppings or fillings and bake on a baking sheet or pizza stone for about 12-15 minutes, or until the crust is golden and the cheese is bubbly.
