01 - Combine lukewarm water, yeast, and sugar in a large mixing bowl. Stir gently and let sit for 5-10 minutes until foamy and activated.
02 - Add yogurt to the yeast mixture and mix thoroughly until well incorporated.
03 - Gradually add flour and salt, mixing continuously until a sticky, shaggy dough forms.
04 - Knead the dough by hand or with a stand mixer for 10 minutes until smooth, elastic, and no longer sticky.
05 - Cover the bowl with a damp cloth and place in a warm, draft-free area. Let rise for 1 hour until doubled in size.
06 - Punch down the risen dough and turn onto a lightly floured surface. Divide into 8 equal portions.
07 - Shape each portion into a smooth ball, then roll into 6-inch rounds approximately ⅓ inch thick.
08 - Preheat a nonstick skillet or cast-iron pan over medium-high heat until hot.
09 - Place one flatbread in the hot pan. Cook for 2-3 minutes until golden brown and puffy bubbles appear.
10 - Flip and cook for 1-2 minutes until golden with light char spots. Remove and repeat with remaining dough.
11 - Brush warm breads with olive oil or melted butter if desired. Cover with a kitchen towel to keep warm and soft. Serve immediately or store airtight for 2 days.
