Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Cut the chicken breast and sweet potato into bite-sized cubes.
In a large bowl, toss the chicken, sweet potato, and broccoli florets with olive oil, turmeric, sea salt, and black pepper until evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20-25 minutes, or until the chicken is cooked through and vegetables are tender.
While the vegetables roast, cook the quinoa according to package directions and set aside.
Place the kale in a small bowl with the lemon juice and a pinch of salt; massage with your hands for 1-2 minutes until the leaves are softened and dark green.
Assemble the bowl by layering the cooked quinoa, massaged kale, and roasted chicken and vegetable mixture.
Drizzle the tahini over the top before serving.
