Preheat oven to 400F and line two baking sheets with parchment paper. Unfold puff pastry on each baking sheet.
Cook pork sausage according to package, breaking into small pieces and until completely cooked through. Set aside to cool for 15 minutes.
In a bowl, mix together softened cream cheese, sausage, pesto, and red pepper flake.
Add half of sausage mixture onto each puff pastry and spread to the edges. Spread about 3/4 cup shredded mozzarella cheese on each.
Fold puff pastry in half horizontally and using a pizza cutter, cut into 10 sticks. Repeat on other puff pastry.
Twist each puff pastry so that they have about 3 twists. Lay flat on baking sheet.
Brush each pastry with egg wash and sprinkle with remaining mozzarella cheese.
Bake for 30-35 minutes or until golden brown. Let cool 10 minutes before serving. I like to dip in marinara sauce!
