Preparation Steps

• Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
• Unfold the thawed puff pastry sheet onto a lightly floured surface. If it's too cold, let it sit at room temperature for a few minutes until pliable.
• Spread the Dijon mustard evenly over the puff pastry, leaving a small border around the edges.
