Puff Pastry Dough (I used scraps from wellington. But you can start with a whole sheet.)
Fresh Spinach, chopped (I used a handful. If using a whole sheet use 1 cup)
1 tbsp All Whites
Roll dough into a rectangle. Brush with All Whites. Spread spinach evenly over dough leaving 1/2 inch on one of the short ends. Lightly sprinkle cheese on top. Sprinkle Sandwich Sprinkle on top. Tightly roll dough from small end with filling. Wrap in plastic wrap. Freeze 40 minutes. Slice about 1/2 inch thick.
Preheat oven to 425. Line a baking sheet with parchment paper.
Bake for 8-10 minutes.
