Whisk together all ingredients for dressing. (Or add ingredients to a jar with a lid and shake to emulsify.)
Add kale to a large bowl. Add in the dressing and massage firmly for 3-5 minutes, until the kale has softened and shrunk considerably in volume.
Toss in the shredded cabbage and green onions. The salad can be served immediately, or it can be marinated for several hours or even overnight and the greens will continue to tenderize. Top with sliced toasted almonds and any other optional add-ins when ready to serve.
