Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Cut the chicken breast into 1-inch bite-sized cubes and place them into a large mixing bowl.
Add the cooked chickpeas, broccoli florets, and sliced red bell pepper to the bowl with the chicken.
Drizzle the extra virgin olive oil over the ingredients and sprinkle with sea salt, black pepper, garlic powder, and smoked paprika.
Toss everything together until the chicken and vegetables are thoroughly and evenly coated with the oil and spices.
Spread the mixture in a single, even layer on the prepared baking sheet, ensuring the pieces are not overcrowded.
Roast for 18 to 22 minutes, or until the chicken is cooked through and the chickpeas have developed a light, crispy exterior.
Remove from the oven and immediately drizzle with fresh lemon juice to brighten the flavors before serving.
