Bread-Bakers v100.n027.3

Is anyone out there familar with Schlotzky's Deli (sandwich shop chain)?

  I just had a really good Mediterranean pizza made on a "herbed sourdough
crust".  This was almost like a French bread, holey and light on the
inside,  not tough like so many sourdoughs.  If anyone knows anything about
this bread-like crust, I'd sure like the recipe to make it at home.
Thanks
