Garlic Bread Grilled Tomato Sandwich

Along with the rest of the United States, Canada, the UK, and perhaps most of the rest of the world, I adore a good grilled cheese sandwich.  The other day we had young friend and his mother to dinner, and said young friend asked the food blogger, "But tell me just how you get a grilled cheese cooked nicely?  No matter what I do, one side burns and the other side's got nada." (Answer:  Don't flash-fry it. Have patience.)  In bookstores (of which there are few except Barnes and Noble or Garrison Keillor's new store, Common Good Books, on Snelling--just a few blocks from my house), there are truly books all about grilled cheese.  Could that be?  Are things out of kilter in the cookbook world? Or are grilled cheese that high up on the menu list?
