Add the shredded cheese to the mixture and mix until combined.
On a lightly floured surface, roll out the puff pastry dough until it is about 1/4 inch thick.
Cut the dough into approximately 3-inch circles using a biscuit cutter or cookie cutter.
Place 1 tablespoon of the corned beef mixture in the center of each circle.
Fold the dough in half over the filling and press the edges together with your fingers to seal.
Place the puffs on a parchment-lined baking sheet and bake for 20-25 minutes, or until golden brown.
Serve warm.
