The number of slices of ham and cheese does not have to be exact. You can use more/less of ham or cheese depending on your personal taste. Cheddar is the most popular choice, but you can also use other cheeses as well, such as Comté, Gouda, Gruyere, Monterey Jack, or Swiss. For an added punch of flavor, add some ranch dressing on top of the ham and cheese before you put the final slice of bread down. [16] X Research source
