On a lightly floured surface, roll out the dough into a thin sheet. Cut out rounds using a 7.5-cm (3-inch) cutter. Place about 10 ml (2 teaspoons) of the filling in the centre of each round. Lightly brush the edges of the rounds with water. Fold the rounds over the filling to form half-moons. Press the edges together to seal. Set aside on a lightly floured baking sheet.
