Wash the chicken thoroughly, dab dry and divide into 10 parts (2 upper and lower legs, 2 wings, 4 breast pieces with bone). For the seasoning marinade, wash the organic orange hot, rub dry.
Cut off 2 slices for garnishing and set aside. Finely grate the skin of the remaining orange. Mix with salt, pepper and oregano, stir in oil. Spread some marinade on the chicken parts.
Onions peel and cut into slices. Peel all oranges so that the white skin is completely removed. Cut oranges into large pieces. Wash potatoes thoroughly and cut them into quarters or halves, depending on size.
Peel the skin from the chorizo and cut the sausage into large pieces.
Mix the potatoes, chorizo, oranges and onions with the rest of the marinade and spread in a fat pan. Place the meat on top, press lightly into the potato mixture. In a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see
manufacturer) cook for about 55 minutes. In the meantime wash oregano, dab dry and pluck coarsely. Remove the chicken pan from the oven and garnish with orange and oregano.
