Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Drain and rinse the chickpeas, then pat them very dry with a clean kitchen towel to ensure they crisp up in the oven.
Cut the chicken breast into bite-sized cubes and chop the red bell pepper into similar-sized pieces.
Place the chicken, chickpeas, broccoli florets, and bell pepper onto the prepared baking sheet.
Drizzle the olive oil over the ingredients and sprinkle evenly with smoked paprika, garlic powder, sea salt, and black pepper.
Toss everything together with your hands or a spatula until well-coated, then spread into a single layer.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the chickpeas are golden and crispy.
Transfer the roasted mixture to a bowl and enjoy immediately while warm.
