I found this recipe on eastvillagekitchen.com and made it with my wife. It came out so good I had to add to my cookbook. If you like Fra Diavolo you'll love this! The version we just made was a little too spicy - I might try cutting down on the red pepper next time - but it was still really delicious. Great over pasta, or on its own as an appetizer (double the serving count for appetizer).
This is an excellent recipe if you like mushrooms. I use a cobination of reconstituted Porcini mushrooms (that I can get dried at my local food store), baby bella, and button mushrooms that I soak in the porcini water. The combination is awesome.
