American cheese rocks, but you must buy the good stuff from the deli counter. Kraft singles and the like all taste like crap. Also, it should be melted, and I prefer the white variety. It's unparalleled for bacon, egg, and cheese sandwiches. Works great on burgers, ham and cheese sandwiches (though muenster and cheddar are great for that, too), grilled cheese, hmm... I usually tear up a slice into my eggs when I make scrambled eggs, too. Yes, American cheese is good (even though it's not technically "cheese").
