I don't care for bacon, it doesn't have much flavor and is often just used for salt, or fat. I leave it out of almost all recipes that call for it and haven't missed it yet.
Yeah, it's just because I've removed pig (and cow) from my diet, for environmental impact and cute cow video reasons.
Had some really nice venison stroganoff last night, though. I grew up seeing too many roadkill deer to really feel for Bambi.
