Cover your hands with oil; this will make it easier to handle the dough. Take the dough and begin forming balls (a little bigger than golf balls) and with a rolling pin or a tortilla maker rolled out or squeeze the dough into circles (you can use plastic film wrap or brushed some vegetable oil into your rolling pin or tortilla maker or both). Make a circle and add the filling (big tablespoon) in the middle, then fold over and press to seal. Repeat until you are out of dough.
Fry in hot oil, until golden brown (in the edges) then put over paper towels to extract all the oil. Enjoy right away.
