Pre heat oven to 180°C and line a large circular baking tray with baking paper.
Unroll the pastry and cut in half lengthways so you have 2 long rectangles. Using a pastry brush, brush the edge of the short sides of the rectangles to join the 2 pieces together and make one large rectangle.
Spoon the cranberry sauce down one side of the rectangle then press the veggie sausages on top of the cranberry sauce.
Brush the exposed pastry with beaten egg and carefully roll the pastry into a long sausage roll shape. Arrange into a circle on the lined baking tray by joining the 2 edges together.
Make around 15 slits (around two thirds of the way through the sausage roll) to create the wreath. Brush with beaten egg and bake in the oven for around 30-35 minutes, until golden brown and the sausage meat is cooked through.
Remove from the oven and serve with extra cranberry sauce.
