Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Pat the chicken breast completely dry with paper towels and cut into 1-inch bite-sized cubes.
Rinse and drain the chickpeas, then roll them between two clean kitchen towels to remove as much moisture as possible for maximum crispiness.
Dice the red bell pepper and zucchini into pieces roughly the same size as the chicken cubes.
In a large mixing bowl, combine the chicken, chickpeas, bell pepper, and zucchini.
Drizzle with olive oil and sprinkle with smoked paprika, cumin, garlic powder, sea salt, and black pepper, tossing until everything is thoroughly coated.
Spread the mixture in a single, even layer on the prepared baking sheet, ensuring the ingredients are not overcrowded.
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 and garnish with freshly chopped parsley before serving warm.
