My family (as an appetizer only!) will make a stuffin outta cream cheese, a little tony c's and cavenders, and pack the tops of those portabellos with it. then we dust a little more Cs and Cavenders on top and smoke away! The are great as is, i bet they'd be good on a bun too! Actually, you can see some of them in the bottom left hand corner of my profile picture. next to the yardbirds.
