2 x 15ml tablespoons regular olive oil
12 chicken thighs (bone in, with skin)
750g chorizo sausages, whole if baby ones, or cut into 4cm chunks if regular-sized
1kg new potatoes, halved
2 red onions, peeled and roughly chopped
2 teaspoons dried oregano grated
zest 1 orange
Preheat the oven to 220°C/gas mark 7. Put the oil in the bottom of 2 shallow roasting tins, 1 tablespoon in each. Rub the skin of the chicken in the oil, then turn skin-side up, 6 pieces in each tin.
Divide the chorizo sausages and the new potatoes between the 2 tins. Sprinkle the onion and the oregano over, then grate the orange zest over the contents of the 2 tins.
Cook for 1 hour, but after 30 minutes, swap the top tray with the bottom tray in the oven and baste the contents with the orange-coloured juices.
