In my mind, you'd not know if this was meat or otherwise! I let my
omni son try it also and he agreed. Tasted like beef.
I guess the only thing that could be obviously noticeable, is the lack of fat content. But I've never actually thought of fast food burgers being very juicy. They tend to be drier. (Some might say, cardboard like!)
This burger was a good alternative option at a stretch. I wouldn't write home about it, but as a quick convenience food, when passing, it did the job. Tasty enough and guilt free!
