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 cube the gold potatoes into 1/2-inch pieces to ensure even cooking.
Slice the zucchini into half-moons and chop the red bell pepper into 1-inch squares.
In a large mixing bowl, combine the chicken, potatoes, zucchini, and bell peppers.
Drizzle with extra virgin olive oil and sprinkle with dried oregano, garlic powder, sea salt, and black pepper.
Toss everything thoroughly until the chicken and vegetables are evenly coated in oil and spices.
Spread the mixture in a single layer on the prepared baking sheet, ensuring nothing is overcrowded.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the potatoes are tender and golden.
Serve immediately while hot and fragrant.
