Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Drain and rinse the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure they get crispy.
Cut the chicken breast into bite-sized cubes and chop the red bell pepper into similar sized pieces.
Place the chicken, chickpeas, broccoli florets, and bell peppers onto the prepared baking sheet.
Drizzle the olive oil over the ingredients and sprinkle with smoked paprika, garlic powder, sea salt, and black pepper.
Toss everything together until evenly coated and spread out in a single layer to ensure even roasting.
Roast in the oven for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the chickpeas are golden and crisp.
Remove from the oven and drizzle with fresh lemon juice before serving in a bowl.
