Anyone who is cool and suave knows that the Garden of Eden had no apple tree, but its design was focused on a large bacon bush...

Crisp!
Thick or thin (but thin is better with crisp toast broken into 4 minute eggs)
Pepper-cured (Black), closely followed by red pepper and jalapeno-cured (but I had some thick sliced chipotle-cured the other day which would knock your socks off).

Nirvana is a bacon and tomato sandwich with sharp Cheddar nestled beneath the bacon and spicy mustard slathered on the tomato (optimally served on well toasted whole wheat or multigrain bread).
