Once your kale is rinsed, massage the 1/2 teaspoon of salt into the leaves. This will help tenderize the kale, making it nice and soft. Leave to sit while you make the dressing, or up to 4 hours.
Make the dressing:
If your tahini is very smooth and "drippy" this will come together easily in a mixing bowl. If it's thicker, a high speed blender makes quick work of it.
Combine the dressing ingredients and whisk or blend until very smooth.
In a large serving bowl, combine all of the salad ingredients.
