Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them very dry with a clean kitchen towel to ensure they get crispy.
Cut the chicken breast into bite-sized cubes and chop the red bell pepper into 1-inch pieces.
Place the chicken, chickpeas, broccoli florets, and bell peppers on the prepared baking sheet.
Drizzle with olive oil and sprinkle with smoked paprika, sea salt, and black pepper, tossing well to coat everything evenly.
Spread the mixture into a single layer and roast for 20 to 25 minutes, or until the chicken is cooked through and the chickpeas are golden.
While the bowl base roasts, whisk together the Greek yogurt, lemon juice, and garlic powder in a small bowl until smooth.
Divide the roasted chicken and veggie mixture into bowls and drizzle the creamy lemon-garlic sauce over the top before serving.
