Shiitakes have tough inedible stems that should be removed. For white mushrooms (called button when small), cremini, and portobellos, trim the spongy tip; the rest is edible.

I added garlic and fresh thyme to the veggies and substituted black pepper Boursin for the goat cheese, which my husband will not eat. I don't understand cooking the onion separately or covering the pans. If I make this again I will saute the onions, then add mushrooms and garlic and cook until the mushrooms are browned, then add the spinach and thyme and stir until the spinach collapses.
Vegan Tip: Although it contains hydrogenated oils, including palm, 'Pepperidge Farm' puff pastry is vegan! Substitute vegan cream cheese or ricotta for the goat cheese (I prefer 'Kite Hill' brand!) Or, 'Follow Your Heart' Parmesan cheese is a great choice, too!
Great recipe, and all the comments are helpful.
I used phyllo puffed pastry instead, and the 14 oz container was a bit too much dough. The topping was delicious, but if you plan to use phyllo pastry instead, you can probably get away with 1/4-1/2 the 14 oz package. I tried this on two dinner guests, and they liked the recipe (both went back for seconds) but there was a lot of left over dough on plates.
