Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Pat the chicken breast and chickpeas completely dry with a paper towel to ensure maximum crispiness.
Cut the chicken into 1-inch bite-sized pieces and slice the red bell pepper into thin strips.
In a large bowl, toss the chicken, chickpeas, and bell peppers with the olive oil, sea salt, black pepper, garlic powder, and smoked paprika until evenly coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 18-20 minutes, or until the chicken is cooked through and the chickpeas are golden and crunchy.
While the tray roasts, place the chopped 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 soften and turn dark green.
In a small ramekin, whisk the tahini with a teaspoon of warm water until it reaches a pourable consistency.
Assemble your bowl by placing the cooked quinoa and massaged kale at the base, then top with the roasted chicken, chickpea, and pepper mixture.
Drizzle the creamy tahini over the top and serve immediately.
