I tried an experiment yesterday that turned out amazingly well. Order your McRib at Mickey Dee's sans sauce and rehydrated onions and when they give it to you, ask for a container of that smoked chipotle BBQ sauce they have for their chicken McThingies and slather that on the pork patty instead. The result is surprisingly yummy.
(Everybody else has been putting recipes on their blogs, so there's mine. :-D )
