To make the turmeric tahini dressing add the tahini, lemon juice, water, and maple syrup to a bowl and whisk until smooth. Add the turmeric, garlic powder, salt, and black pepper. Continue whisking until creamy. Adjust the water if you prefer a thinner dressing. Taste and adjust seasoning as needed.
Add the kale, quinoa, chickpeas, sweet potatoes, and avocado to a large salad bowl. Top with beet sauerkraut, if using. Drizzle with as much dressing as you would like and sprinkle with pumpkin seeds. The remaining dressing will keep for up to a week in a sealed container in the refrigerator.
