Subway I definitely wouldn't consider fast food.
No? What is it? I just lump it in with all those junky chains.
Junky? Geesh, you must be a picky connoisseur. It's not your definition of fast food, which of course is a completely negative connotation. Subway sandwiches aren't really all that bad. They do what they do and IMHO they do it decently. I fail to see what the difference would be between buying a Subway sandwich and making a sandwich at your own house.
Uh...it doesn't take very high standards to be less than thrilled by the quality of food at any fast food establishment, including Subway. But regardless of my views of all fast food, I still consider it the same as McDonalds or Dunkin Donuts.
