There are many ways to make cabbage taste bad, but there are also many ways to make then taste good. Cabbage is tasty, but not my favorite. My favorite vegetable is Carrots. I don't know why, I just like em.
Sauerkraut, rotkraut, kimchi, even steamed cabbage has more of a flavor than raw lettuce.
Indeed you are right Ernie, all these are better then just raw lettuce. That is why I prefer these more then lettuce.
Still waiting for a kimchi burger to appear in the US.
Now that you have said that, the idea has been stolen and and trademarked and it will appear somewhere in America. At least, I hope so....
