Activate the yeast by combining warm water, sugar, and active dry yeast in a bowl; let it sit for 5-10 minutes until foamy.

In a large bowl, mix flour and salt, then add the activated yeast mixture and olive oil, mixing until a shaggy dough forms.

Knead the dough on a lightly floured surface for 5-7 minutes until smooth and elastic, then place it in a greased bowl, cover, and let it rise in a warm place for 1 hour, or until doubled in size.

Punch down the risen dough, divide it into 5 equal portions, and roll each portion into a breadstick shape, about 8-10 inches long.

Arrange the breadsticks on a baking sheet lined with parchment paper, cover them loosely, and let them rise for another 15-20 minutes.

Preheat your oven to 400°F (200°C); if desired, brush the breadsticks with melted butter and sprinkle with garlic powder and parmesan cheese.

Bake for 15-20 minutes, or until golden brown, then let them cool slightly before serving.
