Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into uniform 1-inch cubes and place them in a large mixing bowl.
Rinse and drain the canned chickpeas thoroughly, then add them to the bowl along with the sliced bell peppers and zucchini rounds.
Drizzle the extra virgin olive oil and fresh lemon juice over the chicken and vegetable mixture.
Sprinkle the sea salt, black pepper, garlic powder, and smoked paprika evenly over the ingredients.
Toss everything together with a large spoon or your hands until the chicken and vegetables are well-coated in oil and spices.
Spread the mixture out in a single layer on the prepared baking sheet, ensuring enough space for the air to circulate.
Roast in the center of the oven for 22 to 25 minutes, or until the chicken is cooked through and the vegetables are tender with slightly charred edges.
Remove from the oven and let the pan rest for 2 minutes to allow the juices to redistribute.
Transfer the roasted mixture into a shallow bowl and serve immediately while hot and fragrant.
