Follow these steps to create your Creamy Spinach Corn Savory Croissants:

1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Sauté the Spinach: In a skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant. Then add the chopped spinach and cook until wilted.
3. Mix the Filling: In a bowl, combine the cooked spinach, sweet corn, cream cheese, mozzarella cheese, salt, and black pepper. Mix thoroughly until well combined. If using, add fresh herbs for added flavor.
4. Prepare the Puff Pastry: Roll out the thawed puff pastry on a lightly floured surface. Cut the pastry into triangles, ensuring they are large enough to hold the filling.
5. Fill the Pastry: Place a generous spoonful of the filling at the base of each triangle. Roll the pastry from the base to the tip, forming a croissant shape. Ensure the filling is securely tucked inside.
6. Apply Egg Wash: Place the croissants on the prepared baking sheet. Brush the tops with the beaten egg to give them a beautiful golden color when baked.
7. Bake: Bake in the preheated oven for 25-30 minutes or until golden brown and puffed.
8. Cool: Remove from the oven and let cool on a wire rack for about 15 minutes before serving.
