Oh yes it does have enough salt to stand on its own. I never add salt to either Beyond or Impossible brands. I might add other seasoning if I’m trying to hit a flavor profile (liquid smoke, cajun spices, curry, etc).
You can just plop it out as-is and it’ll cook up nicely. Just don’t squish all the liquid out of it. I’ve had some nasty versions because people get away with poor cooking skills with reql meat and these don’t tolerate the same abuses.
