Place the torn kale in a large bowl. Add the guacamole and massage it into the kale to tenderize the leaves. For the best results, massage with your hands but you can also do this with a sturdy wooden spoon.
Add the carrots and red cabbage to the kale mixture. Massage the salad until combined, or for about 15-30 seconds. Gently fold the black beans into the salad.
Serve immediately, or, for more tender kale, cover the salad and marinate in the refrigerator for 1-2 hours before serving. It's tasty either way!
