Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Pat the chicken breast dry with a paper towel and cut it into bite-sized cubes.
Rinse and drain the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure they crisp up in the oven.
Place the cubed chicken, dried chickpeas, broccoli florets, and chopped red bell pepper onto the prepared baking sheet.
Drizzle the extra virgin olive oil over the ingredients and sprinkle with smoked paprika, garlic powder, sea salt, and black pepper.
Toss everything together with your hands or a spatula until evenly coated, then spread into a single layer.
Roast for 20 to 25 minutes, tossing the ingredients halfway through, until the chicken is cooked through and the chickpeas are golden.
Remove from the oven, transfer to a serving bowl, and garnish with freshly chopped parsley.
