I feel this thread is missing the most important question about breakfast sandwiches, which is why these glorious concoctions are designated with a name that implies it is fit only as a first-meal-of-the-day-repast.
If I had my druthers, I'd be eating a bacon, egg, and cheese sandwich every 1/2 hour through my waking hours. As it stands right now, all I get is boldly shamed by nomenclature when I quite reasonably choose to scarf them down at noon, as a pre-dinner warm-up, when I'm huddled in a cold alley at 3 AM, or really anytime outside of the hours between 6-10 AM.
They should just be sandwiches. Or Ambrosia of the Gods, if you want something a little more distinguished.
