1. Preheat oven to 400°F. In a medium bowl, mix together the drained spinach, crumbled feta, chopped onion, 2 eggs, & the optional fresh herbs. In a small bowl whisk the remaining egg with the water to create an egg wash.

Roll out the puffed pastry & cut into squares, depending on the size of spinach puffs you want. Place a small amount of the spinach mixture onto each square, closer to one corner leaving space between the mixture & the edges. Using a clean kitchen brush, brush the edges of the puff squares, one at a time, with the egg wash. Next, lift one corner of a square & fold it over to the opposite corner, creating a triangle with the spinach mixture inside. Press the edges closed using your fingers or a fork. Repeat this process until all of the squares are triangles (or you can press 2 corners together & leave the spinach exposed). Move the pre-puffs to a parchment lined tray & brush the tops with the rest of the egg wash. Bake for about 20 mins. or until the puffs are nice & golden with a touch of brown. "Watch it. They're still hot." Best served warm.
