Heat the oven to 400°F/205°C
Add your potatoes to a large baking tray with raised sides or in a large roasting dish. Drizzle with 1 tablespoon olive oil. Place the chicken pieces on top in a single layer and drizzle with the remaining olive oil and ½ teaspoon salt.
Place into oven and roast for 25 minutes.
Add the tomatoes, onion, olives, oregano and red wine vinegar. Return to the oven and roast for another 15-20 minutes until cooked through reaching an internal temperature of 165°.
For extra crispy skin broil for 2-3 minutes, or until the chicken is caramelised and slightly charred on top. Remove from the oven and serve immediately.
