Divide dough into 4 pieces and roll into 1/4 inch circles. Tip: to make round shape, using the cupping method I learned working as a teenage pizza maker. Cup your hand around the sides of the dough and move circularly around until you get a round shape. You may need to knead back down as you want a level piece.
Add sauce layer.
On one circle end, add cheese.
Add oregano or other spices.
Fold the circle to make a half circle or half moon.
Join the two halves, with the crimping fork method (like you would see in hand pies) or my favorite is the pinch and fold on top crimp method to give a fancy but homemade edge vibe like in the photo.
