Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Cut the chicken breast into 1-inch bite-sized pieces and ensure the chickpeas are rinsed and patted very dry for maximum crispiness.
In a large mixing bowl, combine the chicken, chickpeas, broccoli florets, and sliced bell pepper.
Drizzle with extra virgin olive oil and sprinkle with garlic powder, smoked paprika, sea salt, and black pepper.
Toss the mixture thoroughly until every piece is evenly coated in oil and spices.
Spread the ingredients in a single layer on the prepared baking sheet, ensuring they are not overcrowded.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the chickpeas are golden.
Remove from the oven and drizzle with fresh lemon juice before serving in a bowl.
