Preheat your oven to 400°F and lightly grease a small oven-safe baking dish.
Cut the chicken breast into bite-sized cubes and place them in a mixing bowl.
Toss the chicken with half of the olive oil, garlic powder, smoked paprika, sea salt, and black pepper until evenly coated.
In the baking dish, combine the cooked brown rice, chopped broccoli florets, and diced red bell pepper with the remaining olive oil.
Nestle the seasoned chicken pieces into the rice and vegetable mixture, spreading them out evenly.
Bake for 20-22 minutes until the chicken is cooked through and the rice edges achieve a light, crispy texture.
Remove from the oven and garnish with freshly chopped parsley before serving warm.
