I love mushrooms so I was anxious to try this recipe. Unfortunately it wasn't as good as I had hoped. The flavor was okay, but the texture of the wet bread was hard to stomach. I won't make this one again.

This was sooo good! I think this will become one of those "must make at Thanksgiving" recipes. I loved the addition of the celery, and the mayo added a nice tangy flavor. Thanks Miller for sharing this recipe...(still not entirely won over on "Haggis"...(LOL!)
