In an effort to lose weight in the past, I've tried Morningstar Farm's "vegetarian bacon". It's edible, but man, it just doesn't come close to the real thing. I'd rather be overweight than give up the good stuff.
See, stuff like that infuriates me. If you're going to eat bacon, you might as well go all out. My girlfriend is vegan and often purchases soy-based meats. One look at it and I'm immediately turned off. There's no sense in making something like bacon "healthy." People know what they're getting into, a glorious, greasy, flavorful, smokey, and meaty piece of meat. None of this vegan BS.
Plus, I have a soy allergy so I can't have it anyways.
Also, I <3 bacon jerky. Said vegan girlfriend bought me a sampler pack from baconfreak.com for Valentine's Day.
