Step:

  1. Preheat oven to 375°

  2. Thaw out puff pastry and put into a deep dish pie pan. I cut off the long corners and filled in any gaps. Blind bake for 10 mins.

  3. Saute onions once they start carmelizing add mushrooms. Once mushrooms are browned add spinach until wilted. Salt and pepper to taste. Let mixture cool

  5. Pour mushroom mixture into the bottom of the puff pastry. Make sure to spread it out evenly so every bite has a little bit ove everything in it.
