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 very dry with a clean kitchen towel to ensure they roast up perfectly crispy.
Toss the cubed chicken and dried chickpeas on the baking sheet with olive oil, smoked paprika, garlic powder, sea salt, and black pepper until well coated.
Roast for 20 minutes, tossing halfway through, until the chicken is cooked through and the chickpeas are golden and crunchy.
While the protein roasts, place the chopped kale in a large mixing bowl with 1 tablespoon of the lemon juice and massage with your hands for 2 minutes until tender.
In a small bowl, whisk together the tahini, the remaining 0.5 tablespoon of lemon juice, and water until the dressing is smooth and velvety.
Assemble the bowl by layering the massaged kale at the base, followed by the roasted chicken, crispy chickpeas, cucumber slices, and thinly sliced radishes.
Drizzle the creamy tahini dressing over the entire bowl and enjoy immediately while the roasted elements are still warm.
