In a large mixing bowl, combine the flour, yeast, and salt.
In a separate bowl, mix the water, olive oil, and sugar if using.
Gradually add the wet ingredients to the dry ingredients, stirring until a dough forms.
Knead the dough on a floured surface for about 10 minutes until it becomes smooth and elastic.
Place the dough in a lightly oiled bowl, cover it with a damp cloth, and let it rise in a warm place until it doubles in size, about 1 hour.
Once risen, punch down the dough and shape it as desired.
