Cheesy Spinach and Mushroom Pinwheels

It's become a tradition in our family to celebrate Christmas Eve with a feast of finger foods. Each year we enjoy all our favorite tidbits, as well as a few newbies like these cheesy spinach and mushroom pinwheels.  They're a breeze to make - the filling is assembled in seconds using a food processor, then spread onto a thawed sheet of store bought puff pastry.  Then you just roll, slice, bake, and devour.  Very easy, very impressive, and very tasty.

4. On a lightly floured surface, unfold the sheet of puff pastry.

5. Brush the top with the egg wash and spread the spinach mixture in an even layer, leaving 1/2-inch border all around.

7. Using a serrated knife, cut the rolled pastry into 1/2-inch pieces and place cut side up on a silicone or parchment lined sheet pan.

9. Cool on sheet pan for 5 minutes before transferring to a cooling rack. Serve warm or at room temperature.
