Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Rinse and thoroughly pat the chickpeas dry with a clean kitchen towel to ensure they get crispy.
Toss the chickpeas on the baking sheet with 0.25 tablespoons of olive oil, smoked paprika, and a pinch of sea salt.
Roast the chickpeas for 20 minutes, shaking the pan halfway through, until they reach a satisfyingly crunchy texture.
While the chickpeas roast, dice the chicken breast into bite-sized pieces and season with garlic powder, salt, and pepper.
Heat the remaining 0.25 tablespoons of olive oil in a large skillet over medium-high heat and cook the chicken until golden and cooked through.
Add the broccoli florets and sliced red bell pepper to the skillet, sautéing for 5-7 minutes until the vegetables are tender-crisp.
In a small bowl, whisk together the tahini and lemon juice with a splash of warm water until smooth and creamy.
Divide the chicken and vegetable mixture into a bowl, top with the roasted chickpeas, and drizzle the zesty dressing over the top.
