For the chicken
- Preheat the oven to 190°C or gas mark 5
- Put the chicken onto a large baking tray and roast in the centre of the oven for 1-1.5 hours or according to instructions on the packaging. Chicken legs require around 30-40 minutes
- Check that the chicken is cooked completely by piercing the thickest part of the leg with a clean knife or skewer. The chicken is cooked when the juices run clear
- To add extra flavour, stuff the chicken with onion, lemon and garlic, before you cook it
- Prepare the potatoes and vegetables while the meat is cooking
For the crumble
- Heat the oven to 200°C/gas mark 6
- Sieve the flour into a bowl and rub the spread in with your fingertips until it resembles breadcrumbs. Stir in the sugar and the oats
- Peel and thickly slice the apples and toss with the sugar and grated orange rind and juice. Transfer the fruit to an ovenproof dish
- Cover the fruit with the crumble mixture and dot with spread
- Bake for 20-30 minutes until the crumble is golden and crisp. Serve warm with plain yogurt
