Hambone,If I had a girlfriend, and if it didn't have to be pork...Tri Tip is the only way I'd go. It's easy. It ain't quick, but it ain't slow. It never fails to impress, and you can really throw some great rubbed flavors at 'em. Smoke too! If they're staying a long time, you can make samishes with leftovers.Good luck with the girlfriend's parents and the cook.
