Not sure but is string cheese actually moz. cheese? I don't have any right now so I haven't a clue. Anyway, when I made them at home this is what I did.
I just took the string cheese and cut them in half. I then made up a breadcrumb mixture with S & P and Italian Herbs. I then dipped them in and egg mixture and then coated them with the breadcrumbs. I fried them in veg. oil.
DH loves Moz. sticks and really like these alot. Another similar thing to do is the same thing but use frozen cheese filled ravioli (thawed of coarse). Thats DH favorite way to eat ravioli. Granted its not low fat but we only eat it maybe once every month or two.
As for a sauce to dip them in I really like Paul Newmans Marinara Sauce. Sometimes I'll make my own but really only like to do this when I have fresh summer tomatoes.
