That’s just a cut up apple.
The sandwich also appears to contain things a Club sandwich normally doesn’t contain.
I believe that is called a “sliced apple”.
Might taste just fine but looking at it, that’s not a form of presentation I’d consider as ‘food porn’.
Why do people do this? There is neither a clubhouse sandwich or any fries in this image.
This looks like a great lunch but why is it so common to call things what they aren’t? “Fries” isn’t a shape. Apple sticks? Slices? Roughly julienned apples?
Put pork flavoured soy on whatever you want, but why the need to call it vegan bacon ya know?
