Unroll the pizza dough and cut it into 4 squares. Fold the corners over so you create an oval shape. Working on one half of the oval, spread some cheese. Now top with taco meat, refried beans, salsa and then more cheese. Fold the top half of the dough over the filling and pinch the seams together with your fingers to seal the filling inside. Place on the prepared baking sheet. Repeat with the remaining dough.
