In a large mixing bowl, combine the warm water and sugar, then sprinkle the yeast on top and let sit for 5-10 minutes until frothy.

In another bowl, whisk together the flour and salt.

Pour the yeast mixture and olive oil (if using) into the flour mixture and stir with a wooden spoon until a rough dough forms.

Turn the dough onto a floured surface and knead for 5-7 minutes until smooth and elastic.

Place the dough in a greased bowl, cover with plastic wrap or a towel, and let rise in a warm place for about 1 hour or until doubled in size.

Punch down the dough, shape into a loaf or rolls, and place on a baking sheet or in a loaf pan.

Cover the shaped dough and let rise for another 30 minutes.

Preheat the oven to 375°F (190°C), then bake the bread for 25-30 minutes until golden brown and hollow-sounding when tapped.
