Preheat the oven to 210°C/410°F (without fan).
Line a large baking sheet with baking paper.
Use a knife, pastry wheel or pizza cutter to evenly divide the puff pastry into 12 equal wedges or triangles.
Lightly brush some egg wash in the centre of the puff pastry sheet, i.e. where all of the tips join.
Place a piece of sausage at the edge of one piece of pastry.
Roll the sausage in the pastry towards the centre of the puff pastry sheet.
Place the covered sausage onto the baking sheet.
Repeat Steps 5, 6 & 7 with the remaining pieces of sausages.
Lightly brush all of the pastries with some egg wash.
If you like, sprinkle with Everything Bagel Seasoning, poppy seeds or sesame seeds. I generally keep half of the pastries plain (for the fussy eaters).
Bake for 15 to 20 minutes, or until the pastries are golden brown.
Serve warm or hot.
