Okay, so here's my favorite kind of sandwich.
You get some fresh, crusty bread. Best if you can make some yourself, otherwise go to a small independent baker. Get two think slices and butter them, not with margarine, butter.
Next, put some cheese on there, I'd suggest a parmesan or a sharp tasty. Then you get a chicken breast, skinless is easier to work with, but the skin just adds some delicious flavour.
Chop it up into chunks and coat it in crumbs or whatever coating you use (I make my own special one). Fry that sucker till it's moist and tender, put that on top of the cheese.
Fry some bacon, top that off. Add lettuce or tomato if you wish, I prefer it without.
Consume and fall into self loathing.
