Some of the post's salad examples (spaghetti, poutine) could be interpreted as starch surrounded by non-starch. Thus I believe the rule would still consider turkey with stuffing to be a salad.
It’s not a salad if it’s a single cohesive unit. If you chopped it up, it could pass as a “turkey salad” I guess, in the sense of a potato salad, but that would still be a stretch.
