Instructions:

1. Preheat the Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it with cooking spray.
2. Prepare the Filling: In a large mixing bowl, combine the ground pork, breadcrumbs, chopped onion, minced garlic, dried sage, dried thyme, salt, and pepper. Mix until well combined.
3. Roll Out the Pastry: Lightly dust a clean work surface with flour. Place one sheet of thawed puff pastry on the floured surface and roll it out slightly to flatten it.
4. Divide and Fill: Cut the rolled-out pastry sheet in half lengthwise to create two long strips. Divide the pork filling evenly between the two strips, placing it in a long sausage shape down the center of each strip.
5. Roll Up the Pastry: Carefully fold one side of the pastry over the pork filling, then fold the other side over to encase the filling completely. Press the edges together to seal, then place the roll seam-side down on the prepared baking sheet. Repeat with the remaining pastry sheet and filling.
6. Brush with Egg Wash: Use a pastry brush to lightly brush the tops of the sausage rolls with beaten egg. This will give them a golden, glossy finish when baked.
7. Score and Sprinkle: Use a sharp knife to score the tops of the sausage rolls diagonally at intervals, creating a decorative pattern. Sprinkle the tops with sesame seeds or poppy seeds, if desired, for added flavor and visual appeal.
8. Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until the pastry is puffed and golden brown and the pork filling is cooked through.
9. Serve and Enjoy: Remove the sausage rolls from the oven and let them cool slightly before serving. Serve them warm or at room temperature as a delicious snack or appetizer.
