Preheat your oven to 400 degrees Fahrenheit and line a large rimmed baking sheet with parchment paper.
Cut the chicken breast into bite-sized 1-inch cubes and rinse the chickpeas, patting them dry with a clean towel.
On the prepared baking sheet, combine the chicken cubes, chickpeas, and sliced red bell peppers.
Drizzle the mixture with olive oil and sprinkle with sea salt, black pepper, garlic powder, and smoked paprika, tossing well to coat evenly.
Roast in the oven for 18 to 20 minutes until the chicken is cooked through and the chickpeas have reached a slight crunch.
While the tray roasts, place the kale in a bowl with half of the lemon juice and massage the leaves with your hands for 1 minute until they become tender and dark green.
In a small ramekin, whisk together the tahini, remaining lemon juice, and a teaspoon of warm water until the dressing is smooth and pourable.
Assemble the bowl by placing the cooked quinoa at the base, followed by the massaged kale and the roasted chicken and veggie mix.
Finish the dish by drizzling the zesty tahini dressing over the top and enjoy immediately.
