Step 1: Activate the Yeast - In a small bowl, combine the warm water, active dry yeast, and sugar. Stir gently and let it sit for about 5-10 minutes until frothy.
Step 2: Mix the Dough - In a large mixing bowl, whisk together the bread flour and sea salt. Make a well in the center and add the yeast mixture, olive oil, and Greek yogurt. Stir until a shaggy dough forms.
Step 3: Knead the Dough - Transfer the dough to a floured surface and knead for about 8-10 minutes until smooth and elastic. If the dough is too sticky, sprinkle in a little more flour as needed.
Step 4: Let It Rise - Shape the dough into a ball and place it in a greased bowl, turning it to coat. Cover with a kitchen towel and let it rise in a warm area for 1-2 hours, or until doubled in size.
Step 5: Preheat the Oven - About 30 minutes before baking, preheat your oven to 475°F (245°C). If you have a pizza stone, place it in the oven to heat up.
Step 6: Shape the Pitas - Once the dough has risen, punch it down and divide it into 8 equal pieces. Roll each piece into a ball, then flatten it into a circle about ¼ inch thick using a rolling pin.
Step 7: Bake the Pitas - Place the rounds on the hot baking sheet or pizza stone and bake for 5-7 minutes, or until they puff up and turn light golden brown. Keep an eye on them, as they can go from perfect to overdone quickly.
Step 8: Cool and Enjoy - Remove the pitas from the oven and transfer them to a clean kitchen towel to keep warm. Allow them to cool slightly before serving.
