It's closer to a cabbage than it is lettuce, actually... and I love the way it tastes, it's really light and evens out a lot of other strong flavors of the other ingredients in dishes... It's also a great source of iron and vitamin K, calcium, and folic acid.
The carrot tops are the most nutritious of any vegetable and you can't even get them in most supermarkets. I guess they go into animal feed.
when I drink coffee sometimes my pee smells like that. never had kale though its something I intend on getting at the store my next trip. There isn't really a food that I don't like though.
