On a lightly floured work surface, roll out the discs of pastry until 1/8 inch (3 mm) thick. Line three 5-inch (13 cm) small skillets or pie plates with a piece of pastry. Top with the meat mixture. Make incisions in the middle of the remaining pieces of pastry and place them over the meat filling. Remove any excess dough. For each pie, fold the edges of the top pastry under the bottom pastry, pressing to seal the edges and crimping with a fork or your fingers.
