If you eat a burger made from seasoned beef, even if you seasoned it at home, it isn’t 100% either.
I’m not defending Taco Bell, but almost nobody eats 100% beef in a taco or burger even when they think they are.
Care to describe what is not beef in the raw 85 or 90% hamburger bought from the local Safeway Store. Are they using pork fat or what?
That' still a far cry from 88% of -from god knows where- beef.
I expect a small percent is TVP.
Look at a McDonalds breakfast burrito, that little round ball of sausage, is not all sausage either.
I suspect it’s part TVP, too. It is cheaper to add TVP to meat than use all meat.
Look at the money saved by using a small amount of TVP, seasoned or not.
I’m not complaining about it. I buy and add TVP to my food storage...
If refrigeration becomes a problem, if a catastrophic event happens and my meat supply from dehydrated, canned and frozen is gone, contaminated etc, I can use TVP for protein...
