Jimmy John's is actually good. They try to steer away from using processed foods. I'll settle for one when I'm in a smaller city as it's often the least 'chain-ish' of the options at hand which are usually chain restaurants if the mom and pop places aren't accessible to me at the time.

Or Chipotle- burrito. No rice, no cheese. Extra extra extra lettuce. Choice of chicken or black beans. Tons of pico de gallo.

Or on East Coast- soups at Hale and Hearty. I just don't do cream based soups.
