Boil rice according to instructions on the package. Drain.
In the meantime, ground walnuts using a food processor or an immersion blender.
Add minced garlic, khmeli suneli, tarragon, turmeric, cloves, cinnamon, coriander, saffron, black pepper and a pinch of salt. Pour about 1/4 cup chicken broth, tahini paste (optional) and white wine vinegar and mix well.
In a pot, heat the remaining chicken broth over medium heat and gradually add the walnut mixture once the broth is warm, stirring constantly. Bring to a boil, add diced chicken breasts and cook for about 10 minutes over medium-low heat stirring occasionally.
In the meantime, roughly chop kale and sprinkle with 1-2 pinches of salt. Knead kale for a minute until it's soft and dark.
Serve satsivi over layers of kale and rice and season to taste. Enjoy!
Notes
Adjust the consistency of the sauce by adding more chicken broth if it's too thick or a bit of flour (start with 1 teaspoon) if it's too liquid.
