What the hell is a banana pepper? If it's got nothing to do with actual bananas, I am going to be disappointed.
Also, I have to say, any sandwich you don't make yourself at home, doesn't count. Or have made for you - at home. Subway is fast food, no matter how you wanna dress it up. I wouldn't even put what McDonalds serve in the running for best hamburger - they're more like edible constructions. A true sandwich is an art form.
