Well, on reading their web site, it appears that they smoke it just like you or I would. It is fully cooked and will last in your fridge for about a week. Just like a turkey that I would cook/smoke. No magic here....
I usually brine my turkey for a day or so, give it it a good seasoning a let it rip in the smoker at about 250 till done. Every 45 minutes I spritz with EVOO to give it a beautiful skin.
