Taco Bell - Taco Salad
KFC (now has roasted strips ... they are good ... don't eat the rice)
McDonald's - salad or burger no bun
Subway - atkins friendly wrap or salad
Jack In The Box - bunless burger or their chef salad (use my own dressing)

I hear Arby's has a new wrap. Seems like the salads at other places all have to many high-carb additions so I just stay away from those unless I know the counts from their website ahead of time.
