Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Cut the chicken breast and red bell pepper into uniform 1-inch bite-sized pieces.
In a large mixing bowl, combine the chicken pieces, chickpeas, broccoli florets, and chopped bell pepper.
Drizzle the extra virgin olive oil over the mixture and sprinkle with dried oregano, garlic powder, sea salt, and black pepper.
Toss everything thoroughly with a large spoon or your hands until the chicken and vegetables are evenly coated in the oil and seasonings.
Spread the mixture in a single, even layer onto the prepared baking sheet to ensure even roasting.
Roast in the oven for 20 to 25 minutes, or until the chicken is cooked through and the vegetables are tender with slightly browned edges.
Remove from the oven and garnish with freshly chopped parsley before serving warm.
