Preheat the oven to 200°C (400°F).

Roll out the puff pastry sheet on a floured surface.

Cut the pastry sheet into 6 equal rectangles.

Place a sausage on each rectangle and season with salt and pepper.

Roll the pastry around the sausage and seal the edges with a little bit of water.

Cut each roll into 3 pieces and place them on a baking tray lined with parchment paper.

Brush the beaten egg over the top of each roll.

Bake in the preheated oven for 20-25 minutes or until golden brown.

Serve hot and enjoy your delicious sausage rolls!
