1. Preheat oven to 350 degrees. Line a baking sheet with parchment paper. 2. Mix the first 6 ingredients together with the egg yolk in a medium-sized mixing bowl until well blended together. 3. Unroll crescent dough and cut each triangle in half making 2 triangles.  In the middle of each one place 1 tablespoon of the spinach mixture.  Fold up the corners of the crescent dough around the spinach mixture making a little “package” and pinch to seal it. Place on baking sheet. When you have finished making all of your little packages, brush each one with the egg white. 4. Bake for 12-15 minutes or until lightly golden brown on top.
