It really is only limited by your imagination. It can be customized to your own likes and dislikes. If your love is processed cheese and white bread, go for it. I think the only mistake is not thinking outside the box.

What a sandwich maker does is make the grilled cheese a little more special. Not only does it make the marks, but it flattens it well and makes for a good cheese-bread ratio.

If you want more cheese, put more cheese, if you want less, put less.
