Activate the Yeast: In a small bowl, combine warm water, sugar, and yeast. Let it sit for 5–10 minutes until foamy.
Prepare the Dough: In a large mixing bowl, mix flour and salt. Add the yeast mixture and olive oil. Stir until a rough dough forms.
Knead the Dough: Transfer the dough to a floured surface and knead for 8–10 minutes until smooth and elastic.
Incorporate the Olives: Gently knead the chopped olives and oregano (if using) into the dough until evenly distributed.
First Rise: Place the dough in a lightly greased bowl, cover with a damp towel, and let it rise in a warm spot for 1–1.5 hours until doubled in size.
Shape the Loaf: Punch down the dough, shape it into a round or oval loaf, and place it on a parchment-lined baking sheet.
Second Rise: Cover and let the dough rest for another 30 minutes. Meanwhile, preheat the oven to 400°F (200°C).
Bake: Bake for 25–30 minutes or until golden brown and hollow-sounding when tapped.
Cool & Serve: Let the bread cool on a wire rack before slicing. Enjoy!
