It doesn't come cheap; a 6-inch ran me $5.25.
The sub is one of three "Off-the-Menu Specials" that Subway is currently only offering here in Southern California.
They don't actually cut the slices smaller or anything so there were four thick, crunchy apples along with the chicken, veggies, cheese, and bread I was trying to cram in my pie hole (basically it'd be better if they cut them smaller). The apples were not very sweet at all; the green ones in particular were more (really) sour than anything (they were like the lemons of the apple world).
The bacon similarly gets lost and imparts a slight smoke flavor here and there. Even with the toasting, it's not crispy at all.
The barbecue was very sweet and tangy, with the apples lending a fruity note. It tended to overshadow the rest of the sandwich.
The spinach wasn't really felt or heard/tasted but the cucumbers provided a refreshing, watery crunch.
Overall, Subway's Autumn Roasted Chicken Sub just didn't quite mesh for me. While I liked the various textures, taste-wise, it was like barbecue sauce with odd notes of everything else. If you try it, I recommend foregoing the barbecue sauce to get a better, less busy sense of the rest of the sandwich.
