Place the beets, radishes and red onion on a baking sheet lined with foil. Drizzle them with olive oil, salt and pepper. Toss well. Bake for 18 to 20 minutes.
Remove from the oven and give the vegetables a toss. Push them to one side just enough to make room for the kale.
Drizzle the kale with a little bit of olive oil and a sprinkle of salt. Toss and return to the oven. Roast for 8 - 10 minutes.
Assemble individual bowls with the quinoa, vegetables and garbanzo beans. Serve with the Turmeric Tahini Sauce.
To Make the Turmeric Tahini Sauce
In a small bowl, combine the olive oil, tahini, lemon juice, garlic and turmeric. Add 2 tablespoons of water and mix well. Add more water if you need to thin it out a bit more. Season with salt and pepper to taste.
