Preparation: Place the oven rack in the center of the oven and preheat your oven to 425 degrees F (218 degrees C). Line a baking sheet with parchment paper.
Roll out 2 sheets of puff pastry, just to smooth out any creases. You can cut the corners off to make each sheet into a circle or you can leave it a square so as not to waste any puff pastry.
Assemble: Place 1 sheet of puff pastry on the prepared baking sheet. Evenly place the ripped ham on top of 1st puff pastry, and sprinkle a layer of shredded cheese blend.
