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 paper towel to ensure maximum crispiness.
Cut the chicken breast into bite-sized cubes and slice the red bell pepper into thin strips.
Place the chickpeas, chicken cubes, broccoli florets, and bell pepper strips onto the prepared baking sheet.
Drizzle the olive oil over the ingredients and sprinkle evenly with sea salt, black pepper, garlic powder, and smoked paprika.
Toss everything together with your hands or a spatula until well coated, then spread into a single layer.
Roast in the oven for 20 to 25 minutes, tossing halfway through, until the chicken is cooked through and the chickpeas are golden and crisp.
Transfer the roasted mixture to a bowl and serve immediately while hot.
