Cheese as well, especially anything from Kraft. We can also include Tofu, Tempeh, Natto, Nori, and stuff like Kimchi(which has raw oysters tossed into it to help "seed" the bacteria-process. Yummo).
I'm trying hard to think of an exact similarity--I could compare it to some protein-rich plants, as well as fungi, which we eat regularly. Lots of things are "living" to some point or another, some cheeses even incorporate molds into them somehow--It's just how things are, and how humans eat. I'd see this as just another iteration of our wide diet.

Would eat it for sure! (so long as it was never hooked up to any form of a central nervous system... are we talking about just growing up some muscle tissue?)
