Preheat oven to 400°F and line a baking sheet with parchment paper.
Drain and rinse the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure maximum crispiness.
Place the chicken breast and dried chickpeas on the prepared baking sheet.
Drizzle with olive oil and sprinkle with sea salt, black pepper, smoked paprika, and garlic powder, tossing to coat evenly.
Roast for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the chickpeas are golden and crunchy.
While roasting, whisk together the Greek yogurt, tahini, and lemon juice in a small bowl until smooth.
Slice the roasted chicken into thin strips or bite-sized cubes.
Build the bowl by layering the baby spinach and diced cucumber, then topping with the roasted chicken and crispy chickpeas.
Finish by drizzling the creamy tahini dressing over the top.
