Presumably they've made it taste weird and terrible, just like they everything else they get their hands on. How do you mess up things like bread or lettuce? How does one actually make a completely flavorless cheese? Subway bravely finds a way. You have to choose all the spiciest options available just to make it taste somewhat salty Most hilariously they even screw up toasting a sandwich, which is usually the great equalizer to make bad sandwiches at least tolerable. Their ovens are like some kind of pinpoint blasting system that chars certain parts of the bread, and reduces any exposed vegetables to a disgusting gelatinous slop. meatball sub toasted is the one tolerable thing there and the cookies because well they're cookies Pretty much. And even that I have them nuke instead of toasting.
