Meanwhile, squeeze most of the water out of the spinach and place it in a bowl. Add the onion mixture, green onions, Gruyere, Parmesan, and eggs. spiced crackers, salt, black pepper, nutmeg, and pine nuts. Mix well.
3. Unfold one sheet of puff pastry and place it on a parchment-lined baking sheet. Spread the spinach mixture in the center of the pastry, leaving a 2.5 cm border around the edges. Brush the edges of the pastry with beaten egg. On a floured board, roll out the second sheet of puff pastry until it's 2.5 cm longer in each direction.
