This sounds sooooo good. I found it in the bon appetit magazine and can't wait to try it. If you get to it first, let me know what you think. The preparation time has not been added because I've yet to make this, and I've guesstimated the time needed to cook.

LOVE, Love, love this recipe! It is so yummy. I add a little garlic to the mushrooms as they are cooking, for some extra flavor. Occasionally, I will use button mushrooms or baby bellas and the sandwich is still divine. I have made it for friends and have received WOW reviews. Devine.

I have been wanting try something like this for a long time. We loved these. I used toasted onion rolls for the bread and large portabella mushroom caps. I had a few slices of bacon left over from Sunday brunch so I fried those up, discarded most, but not quite all of the grease, added the butter and a little basil flavored olive oil and fried the caps in that, melted a slice of swiss cheese on top of the caps and added a couple half slices of bacon. Amazing!
