Pesto and Parmesan Puff Pastry Rolls: A Delicious Snack for Any Occasion

1. Preparing the Puff Pastry
First things first, preheat your oven to 180°C (gas mark 6). While your oven is heating up, unroll the puff pastry onto a clean, flat surface. Ensure the pastry is smooth and not creased to make rolling easier later.
