Combine the oil, lemon juice, garlic and honey in a bowl. Season with pepper and whisk to combine. Place the chicken on a large plate. Pour over half the lemon mixture and turn to coat. Cover and place in the fridge for 10 minutes.
Pierce potatoes with a fork four times. Microwave for five minutes on high/100%, they will still be firm. Remove from the microwave and wrap together in foil. Set aside for 10 minutes.
Preheat oven 220 °C (200 °C fan-forced). Cut potatoes into chunks and place into large roasting pan lines with baking paper. Drizzle with the remaining lemon mixture. Roast for 20 minutes.
Meanwhile, heat a large non-stick frying pan over high heat until hot. Add two chicken fillets and cook for 2 minutes each side until golden. Repeat with remaining chicken.
Place chicken into the roasting pan with potatoes and roast together further 5-8 minutes, turning the potatoes occasionally until chicken is cooked through and potatoes golden and crisp.
Sprinkle over the parsley and serve with salad or vegetables.
