I am not a veggie, nor doing South Beach, but you may get better results if you also post this in the "Veggie Chicks" portion of this forum (down toward the bottom of the sub-forum page). Good luck!
Squeak is right... there's a link for it here, Edie... http://www.3fatchicks.com/forum/forumdisplay.php?f=121
You may find some recipe ideas in there somewhere which I'm sure could be adapted for use with South Beach.
