Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Drain and rinse the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure they get maximum crunch in the oven.
Cut the chicken breast into bite-sized pieces and place them on the baking sheet along with the dried chickpeas.
Drizzle the chicken and chickpeas with extra virgin olive oil, then sprinkle with garlic powder, smoked paprika, sea salt, and black pepper, tossing to coat evenly.
Spread the mixture in a single layer and roast for 20 to 25 minutes, tossing halfway through, until the chicken is cooked through and chickpeas are golden brown.
While the protein roasts, place the kale in a large bowl with half of the lemon juice and massage the leaves with your hands for 2 minutes until they are dark green and tender.
In a small jar, whisk together the tahini and the remaining lemon juice, adding a teaspoon of warm water at a time until the dressing is smooth and pourable.
Assemble the bowl by placing the massaged kale at the base, topping with the warm roasted chicken and crispy chickpeas, and finishing with a drizzle of the velvety tahini dressing.
