Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Pat the chicken breast and chickpeas completely dry with a paper towel to ensure they roast to a perfect golden crisp.
Slice the chicken into bite-sized pieces and toss them on the baking sheet with the chickpeas and sliced bell peppers.
Drizzle with olive oil and sprinkle with cumin, garlic powder, sea salt, and black pepper, tossing until every piece is evenly coated.
Roast in the oven for 20 minutes, or until the chicken is cooked through and the chickpeas are slightly crunchy.
While the tray roasts, place the kale in a bowl with half of the lemon juice and massage with your hands for 2 minutes until the leaves are tender.
In a small jar, whisk together the tahini, remaining lemon juice, and a teaspoon of warm water until the dressing is silky and pourable.
Assemble your bowl by layering the cooked quinoa, massaged kale, and the warm roasted chicken and veggie mixture before finishing with the zesty tahini drizzle.
