I actually find Subway to be low carb friendly because you can get any sub as a salad, they have lots of low carb veg (not just lettuce and tomato) and if you want, you pay extra for double meat.

Subway used to have a low carb wrap option, but that went away. The wraps are now huge tortillas.

And like Ms. Arielle said, while you can always throw away the bun from a buger, you risk losing the cheese.

In my neck of the woods, Subway is one of the cheaper low carb options for fast food.
