In a large mixing bowl, combine yogurt, water, and baking powder. Mix well until smooth.

Gradually add flour, salt, and vegetable oil to the wet mixture. Gently knead to form a soft dough, being careful not to over-knead.

Divide dough into ten equal portions. Roll each portion into a disc about the size of a dessert plate, keeping the dough covered to prevent drying out.

Heat a skillet over medium heat. Flatten each dough disc and cook in the skillet, turning once, until both sides are golden brown. No additional oil is needed.

Brush each bread round with butter and serve warm.
