Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Thaw the frozen spinach in warm water, then drain and squeeze out excess moisture.

In a large bowl, mix the spinach, ricotta, Parmesan, minced garlic, salt, black pepper, and 1 egg until smooth.

Roll out the puff pastry sheets on a lightly floured surface to ensure they are even.

Spread filling over the pastry, roll tightly, and chill in the refrigerator for 10 minutes.

Slice the chilled rolls into 2-3 pieces and place on the baking sheet. Brush with egg wash and sprinkle with sesame seeds.

Bake for approximately 30 minutes or until golden brown.

Let cool slightly before serving warm with your favorite dipping sauce.
