Thaw the puff pastry if you havent already. Leave it on the counter till soft enough to handle.
Add fresh spinach to a bowl. Pour boiling water and let sit for 3 minutes, then drain and use. If using frozen, thaw , squeeze excess moisture and use.
Add the drained spinach to a bowl. Add cream cheese* (see note to make your own), herbs and spices. Mix well, taste and adjust flavor.
Place the 1 puff pastry sheet on the other and roll it out to a 12 by 14-16 inch rectangle. Spread the spinach mixture on rolled puff pastry evenly. Roll the puff pastry to make a roll. This roll will be soft at this point. Refrigerate or freeze to harden, about 1 hour. (at this point you can leave the roll refrigerated for upto a day, then slice and bake when needed)
Slice with a sharp knife or a serrated knife into 1/2 inch or less thickness. Place on parchment lined baking sheet and bake at 400 deg F for 25 to 30 mins or until golden. Cool for a few minutes before serving. Store on the counter for the day and refrigerated for upto 3 days.
