Creating the Blue Cheese Walnut Thyme Puff Pastry Twirl is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare Puff Pastry: On a lightly floured surface, roll out the thawed puff pastry sheet to smooth it out.
3. Mix Filling: In a bowl, combine crumbled blue cheese, chopped walnuts, thyme, salt, and pepper. Stir until well blended.
4. Spread Filling: Spread the filling evenly over the puff pastry, leaving a small border around the edges.
5. Roll It Up: Starting from one long edge, carefully roll the pastry into a tight log. Make sure the filling stays inside as you roll.
6. Slice: Use a sharp knife to slice the rolled pastry into 1-inch thick rounds.
7. Arrange: Place the pieces cut-side up on the prepared baking sheet, ensuring some space between each twirl.
8. Egg Wash: Brush the tops of each twirl with the beaten egg for a golden finish.
9. Bake: Bake in the preheated oven for 25-30 minutes or until golden brown and puffed.
10. Cool: Once baked, allow them to cool for about 5-10 minutes before serving.
