I don't have an actual recipe for you, but I love the Portobello Ravioli at Olive Garden. They chop the shrooms up and put them in raviolis and have an incredible smoky gouda sauce over them. I swear they could put 3 pounds of it in front of me and I'd probably eat it all.
I often grill the caps and use them in place of burgers, on a bun with a little cheese and mayo. Sometimes dh will grill them, slice them, then make a dip type of thing out of cream cheese and garlic (I think, will ask later) and although it doesn't sound that good, it reallly is!
Will check my Moosewood cookbook for more
