Preheat oven to 375 degrees F. Line a baking tray with parchment paper. Gently roll thawed pastry onto a flat surface and spread evenly with Dijon mustard. Cover the pastry with a layer of IL Villaggio Speck PGI. Sprinkle IL Villaggio Parmigiano Reggiano evenly on top. Roll the puff pastry tightly, beginning with the longer side. Cut into 1-inch thick sections and arrange in a single layer on a baking sheet.
Bake for 8 – 10 minutes, or until golden brown and crisp.
