Cheesy Pigs in a Blanket

Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.

Roll out pastry on a lightly floured work surface and cut into 12 rectangles that are approximately the same length as the sausage.  Place a piece of sausage in the center of the dough and place a cheese stick on top of the sausage. Roll the pastry around the sausage and cheese and press to seal the edges.  Repeat with remaining sausage, cheese and pastry, and place the rolls, seam side down, on the prepared baking sheet. 

Brush egg lightly over each roll. Using a small sharp knife, cut 3 very small slits into the top of each roll. 

Bake in the preheated oven until well puffed and golden brown, 17 to 20 minutes.  Serve with marinara for dipping.
