What is in Schlotzsky's "signature dressing" that is on "The Original" sandwich? - sandwich dressing

If you've already seen and tried Schlotzsky's, the original sandwich, you know how good it is. Well, I have in my town (the nearest is about half two), so I need to manipulate the bread (in other channels such as Quiznos) to. If I knew what the signing of the clothing that would be able to reproduce the original! (I will not deceive Schlotsky dollars, like I do a lot, but I have not with me, and I have with what I was doing, I would be happy if they moved, my city, but probably not important enough to the company a chance.)
In any case, no one knows what in a dress?
