Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a skillet, heat olive oil over medium heat. Add minced garlic and sauté for about 30 seconds.

Add chopped spinach to the skillet and cook until wilted, about 2-3 minutes. Season with salt, black pepper, and dried herbs if using.

Remove from heat and let cool slightly.

Roll out the thawed puff pastry into a rectangle measuring approximately 10x12 inches on a floured surface.

Spread the cooled spinach mixture over half of the pastry and sprinkle with crumbled feta.

Fold the other half of the pastry over the filling and press down to seal.

Cut the folded pastry into 1-inch strips and twist each strip gently.

Place the twisted strips on the prepared baking sheet and brush with beaten egg for glaze.

Bake for 15-18 minutes until golden brown.

Let cool slightly on a wire rack before serving.
