It’s called tofu & is made from soy beans. It is a real thing.

No, it's not called "tofu". Tofu is tofu. Fake meat is made from a laundry list of things that aren't meat (but that cows would eat). At least one brand brags about not using soybeans ...

Here's the ingredients list for "beyond beef" (AKA Cattle Feed)
