Now, let’s get cooking! Follow these simple steps to bring these rolls to life:

1. Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
2. In a skillet, melt the butter over medium heat. Add the garlic and sauté until fragrant, about 1 minute.
3. Add the shrimp to the skillet, season with salt and pepper, and cook until pink and opaque, about 3-4 minutes. Stir in the lemon juice and parsley, then remove from heat.
4. In a large bowl, combine the cream cheese, mozzarella, and Parmesan. Mix in the cooked shrimp and any juices from the skillet.
5. Roll out the puff pastry on a lightly floured surface. Cut into squares about 4 inches wide.
6. Spoon about 2 tablespoons of the shrimp mixture onto each square. Fold the corners up and over the filling, pinching the edges to seal.
7. Place the rolls on the prepared baking sheet and brush with the beaten egg.
8. Bake in the preheated oven for 20-25 minutes, or until the pastry is golden brown.

And there you have it, a dish that’s sure to please and impress, without the hassle of complicated steps.
