Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

Lightly dust a clean surface with flour, unroll the thawed puff pastry, and roll it out to about ¼ inch thick.

Cut the rolled-out puff pastry into long, thin strips, about 1/2 inch wide.

Wrap each vegetarian sausage in a strip of puff pastry, overlapping as needed to create the mummy effect.

Place the wrapped sausages on the baking sheet and bake for 14-16 minutes until golden brown.

Cool slightly, then use mustard or ketchup to add eyes on each mummy.
