Cinnamon-mustard Chicken with Sweet Potatoes and Peppers

Flavour the chicken: Preheat the oven to 240°C (220°C fan oven), gas 9. Mix the mustard, cinnamon and apple juice in a large ovenproof dish or roasting tin. Add the chicken, turning the pieces over several times to coat them in the apple dressing. Set aside.

Par-boil the sweet potatoes: Put the sweet potato wedges in a large pan. Pour in boiling water to cover and boil for 5 minutes.

Combine the ingredients: Drain the sweet potatoes, then add them to the chicken together with the onions and peppers. Turn all the vegetables in the dressing to coat them evenly, then turn the chicken thighs once more and leave them skinned side up.

Roast and serve: Season the ingredients to taste and drizzle over the oil. Roast for 20 minutes or until the chicken and vegetables are cooked and well browned. Test the chicken is cooked by piercing the thickest part with the point of a knife; the juices should run clear, not pink. Serve.
