Turkey bacon just sounds so wrong...so, well, artificial...I mean, if its cured and smoked turkey strips, fine, but bacon it is not. The same way I don't want mock turkey legs made out of pork.
On second thought, those might be pretty dang tasty! Turkey made out of bacon! Its a thanksgiving MIRACLE!
Back bacon (sometimes known as canadian bacon), which you can make yourself fairly easily, is a great lower fat alternative, but anything that is "bacon" is cured, and anything cured is high in sodium at some level. Can't cure without salt!
