Combine the sourdough starter, and kefir a medium sized bowl. Whisk together until combined.

Add the baking powder, salt and flour. Stir to combine, just until the dough comes together. It will be somewhat sticky. Cover with a damp cloth or plastic wrap and let the dough rest in a warm place for 2 – 3 hours.

Once the dough has rested and risen just a little bit (doesn't have to rise much) transfer to a lightly floured service and knead for 1-3 minutes

Cut and divide the dough into 8 pieces.

Preheat a heavy skillet or pan over medium-high heat.

With a rolling pin roll each piece out to about 1/4-inch thickness.

Brush the dough with water and place it water-side down in the skillet or pan. Cook for about 1-2 minutes until the dough bubbles and releases easily from the skillet. Flip and cook for an additional 30 seconds to one minute.

Place the flatbread on a cooling rack and repeat for remaining pieces!

Serve with hummus, onion dip or plain!
