Subway Club Sub, everything but jalapenos (and, now, cucumber). Salt, pepper, mayo, oil and vinegar.
Only do it about 5 times a year, but they actually have known what I wanted when I walk in the door (same owner, 12+ years!).
Maybe not the best, but my other local joints are McD's and Taco Bell.
Yeah, not a lot of meat, but filling and good (IMO).
Not quite as good when on the road.
