This bread was recommended on a low carb facebook group. It's made with whey protein as the flour substitute and is only 1 carb per slice. I guess there are also a lot of variations listed here as well.

I'm just curious if anyone has made this before? I'd like to try it out, but want to hear opinions before I shell out the cash for the whey protein. (They suggest only two brands that work with the recipe.)
