Oh, oh, oh, I know! :heh: The short answer is heaven on earth! It's a breakfast sausage - such as Jimmy Dean - carefully removed from the package and thrown in the smoker, on the grill, etc, and cooked at various temperatures - depending on who you ask - to an internal temp of 165 to 170. I cook mine at about 250 degrees for a couple of hours. They can be either naked - straight from the package - or stuffed with anything you can imagine and wrapped with bacon. Just do a search such as "what is a fattie" and you'll get all kinds of advice, pics, etc! Man, are you in for a treat! I just cooked my first one about a month ago, and right now my freezer has three or four rolls in it just waiting on the next cook! It's become standard practice here to cook a fattie any time I smoke anything else!
