The traditional grilled cheese sandwich is American cheese between two slices of white bread. This version is a ooey-gooey classic (and kid favorite), but there are so many ways it jazz it up. Experiment with different breads and cheeses. Add a slice of tomato, pickles, grilled onions, ham, or bacon to make the grilled cheese truly divine. Serve with a bowl of tomato soup on the side for dunking.
