Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Pat the chicken breast dry and cut into bite-sized cubes, then drain and rinse the chickpeas thoroughly.
Place the chicken and chickpeas on the baking sheet, drizzle with olive oil, and sprinkle with sea salt, black pepper, garlic powder, and smoked paprika.
Toss everything well to coat and roast for 18-20 minutes until the chicken is cooked through and the chickpeas are slightly crisp.
While the protein roasts, whisk the tahini and lemon juice in a small bowl, adding a teaspoon of warm water at a time until it reaches a smooth, pourable consistency.
Massage the chopped kale with a tiny pinch of salt in a large bowl to soften the leaves and make them more tender.
Assemble the Buddha bowl by layering the cooked quinoa and massaged kale as the base.
Top the grains and greens with the roasted chicken and chickpeas, then finish by drizzling the creamy tahini sauce over the entire bowl before serving.
