3. Add chopped spinach to the skillet and cook until wilted. Season with salt and pepper. Remove from heat and let cool slightly.
4. Roll out puff pastry on a floured surface and cut into squares (approximately 4×4 inches).
5. In a bowl, mix the cooked spinach with feta cheese.
6. Place a spoonful of the spinach mixture in the center of each pastry square.
7. Fold the pastry over to form triangles, sealing the edges with a fork.
8. Brush the tops with beaten egg and sprinkle with sesame seeds if desired.
9. Bake for 20-25 minutes, or until the pastries are golden brown.
