Directions

1. 1
   Dust a flat work surface lightly with flour. Unroll puff pastry sheets; roll each out into a 10x15-inch rectangle. Spread a thin layer of Dijon mustard over puff pastry. Cover mustard with a layer of pastrami slices, followed by a layer of Swiss cheese slices. Roll puff pastry up tightly like a jelly roll. Wrap in plastic wrap and refrigerate for 1 hour, or up to 24 hours.
2. 2
   Preheat oven to 350 degrees F (175 degrees C). Line 2 baking sheets with parchment paper.
3. 3
   Slice puff pastry rolls into 1/4-inch-thick slices and lay on the prepared baking sheets. Brush tops with beaten egg and sprinkle with caraway seeds.
4. 4
   Bake in the preheated oven until pastry is lightly browned, about 12 minutes. Let sit for 1 minute on baking sheet before removing.
