Preheat the Oven: Begin by setting your oven to 200°C (392°F). This step is crucial for achieving that perfect golden-brown finish on your sausage rolls.

Mix Filling: In a large bowl, combine the pork mince, French onion soup mix, ketchup, Worcestershire sauce, and mustard. Give everything a good stir, and sprinkle in some pepper to enhance the flavors.

Prepare Pastry: Take the puff pastry sheets and cut each one in half. Shape a log of the savory pork mixture along each half, ensuring an even distribution for delightful bites.

Seal the Rolls: Whisk together the egg and milk. Brush along one side of the pastry so that it sticks when you roll it over the filling. Press down to ensure a tight seal, preventing any leaks during baking.

Cut and Bake: Slice each log into 6-8 pieces, giving you bite-sized treats. Arrange them on a lined baking tray and generously brush the tops with the egg mixture for that mouth-watering gloss.

Bake: Slide your tray into the preheated oven and bake for 20-25 minutes. Keep an eye on them until they turn golden brown and are cooked through, filling your kitchen with that irresistible aroma.
