Preheat Your Oven: Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
Prepare the Filling: In a large bowl, combine the sausage meat, minced garlic, grated Parmesan, and chopped herbs. Season it with salt and pepper to taste.
Roll Out the Pastry: On a floured surface, roll out the puff pastry to a thickness of about 1/4 inch.
Cut the Dough: Divide the pastry into rectangles (about 4 inches by 6 inches).
Fill the Pastry: Spoon a portion of the sausage mixture onto one side of each pastry rectangle and carefully roll it up to enclose the filling. Seal the edges by pressing down with a fork.
Egg Wash: Brush the tops of the rolls with the beaten egg to give them a beautiful golden color when baked.
Bake: Place the rolls on the prepared baking sheet and bake for 20-25 minutes or until golden brown.
Cool and Serve: Allow to cool slightly before serving. Enjoy these scrumptious snacks warm or at room temperature.
