Alright, might as well open myself up to the gunfire...but a few years ago, when I was still living with my wife and kids, and the boys were young, I actually made "White Castle" stuffing for the thanksgiving bird. The recipe is available in their restaurants, and I believe, on their website. Basically you take a bunch of their burgers (fully cooked), crumble 'em up, add a few ingredients, and stuff 'em in the bird.
And, if you really thing about it...the burgers are pretty much loaded with onion, the soft rolls, the broken up beef, well, it's not as much of a stretch as it sounds at first. Anyway, the boys had a great laugh at it, it was NOT awful, and for you skeptics, no, it was not at all a contributing factor to the marriage ending!
