Roll out the first pastry sheet

• Lightly flour the work surface and place the first puff pastry sheet on a piece of parchment paper.
• Slightly roll it out with a rolling pin to thin it a little.

Spread the filling and top with the second sheet

• Slightly roll out the second puff pastry sheet and place it directly on top of the filling.

Score the pattern

• With a sharp knife, make vertical cuts down the whole sheet.
• Tilt the tray and make diagonal cuts in the opposite direction to create a diamond pattern.

Brush with egg and add toppings

• Beat the remaining egg and brush it over the entire surface for a golden finish.
• Scatter the sesame seeds, za'atar and everything bagel seasoning, alternating for a decorative design.

Bake

• Preheat the oven to 190 °C (375 °F).
