Preheat your oven to 425°F (220°C).

Unroll the thawed puff pastry sheets on a lightly floured surface. Roll them out to about ¼ inch thickness.

In a bowl, mix the sausage meat with salt, pepper, and optional herbs until well combined.

Cut the pastry sheets into strips, approximately 4 inches wide, and place a line of sausage meat down the center of each strip.

Fold the pastry over the sausage filling, rolling it tightly to enclose the meat. Pinch the edges to seal and cut into desired lengths.

Beat the egg and brush it generously on top of each roll.

Place the assembled rolls on a lined baking tray and bake for 20-25 minutes or until golden brown and flaky.

Let them cool for a few minutes before serving.
