Yes. As kale is normally tough, it's important that you massage it before adding it to a salad. You just need a sprinkle of salt and a few minutes rubbing the kale leaves between your fingers. The more you massage it, the more tender it will get. I don't usually go overboard with massaging the kale as it will soften up more once it's mixed with the salad dressing. If you like it extra tender, you can massage it with a little oil or lemon juice along with the salt. You can even mix it with some of the salad dressing and let it sit for 5-10 minutes before adding the other ingredients.
