People who say stupid things like "soyboy" have never experienced chronic heartburn/acid reflux. I love a good steak. But if I did red meat regularly I'd burn through my esophagus. Soy is a perfectly good substitute that doesn't agitate me and in most things you can't tell it's there.
Substitute half of ground beef in any Midwestern casserole with soy crumbles and I'm 95% sure none of these meat babies would be able to tell.
