Publix deli subs are so much better than Subway, as are Jersey Mike's sandwiches. It's all about the bread!
As for actual "bad for you" fast food:
- Krystal corn dogs, chili cheese pups, Krystal with cheese
- Chic-fil-a fried chicken sandwich, cole slaw
- Wendy's spicy chicken sandwich and baked potato
I try not to eat any of the three above as much as possible.
