1Preheat your oven to 200°C (392°F).
Roll out the puff pastry sheet on a lightly floured surface.
Place the vegetarian sausage in the center of the puff pastry sheet.
Fold the pastry over the sausage and seal the edges by pressing them together.
Cut the roll into smaller pieces, about 2 inches each.
Beat the egg in a small bowl to create an egg wash.
Brush the top of each roll with the egg wash.
Sprinkle sesame seeds on top of the rolls.
Place the rolls on a baking sheet lined with parchment paper.
Bake in the preheated oven for 20-25 minutes, or until the pastry is golden brown and crispy.
Remove from the oven and let cool slightly before serving.
