Prepare the dough: In a large mixing bowl, combine the flour, sugar, yeast, and salt. Gradually add the warm water and olive oil. If using yogurt, add it at this stage for extra tenderness. Mix until the dough starts coming together.

Knead: Turn the dough onto a lightly floured surface and knead for about 8-10 minutes until smooth and elastic. Alternatively, you can use a stand mixer with a dough hook attachment for 5-6 minutes.

First rise: Place the dough in a lightly oiled bowl and cover it with a clean towel or plastic wrap. Let it rise in a warm spot for about 1-1.5 hours, or until doubled in size.

Shape the bread: Once risen, punch down the dough and divide it into 2 equal portions. Shape each portion into an oval or round loaf. Place the loaves on a parchment-lined baking sheet.

Final rise: Cover the shaped loaves and let them rise again for 30 minutes.

Preheat the oven: While the dough rises, preheat your oven to 220°C (430°F).

Add the glaze: Brush the tops of the loaves with olive oil and sprinkle sesame or nigella seeds. You can also make traditional crisscross patterns on the top with a knife or your fingers.

Bake: Bake for 15-20 minutes, or until golden brown and hollow-sounding when tapped on the bottom.

Cool: Let the bread cool on a wire rack before serving.
