1. In a bowl, mix all the ingredients except the chicken. Rub the chicken well with the marinade and place it in a baking dish.
2. Cover the chicken with non-stick parchment paper and aluminum foil and bake in a preheated oven at 200°C (top/bottom heat) or 180°C (fan oven) for 1 hour. Uncover and continue baking for another 30 minutes.
3. Meanwhile, prepare the rice: In a small pot, add plenty of water and put in the rice bags. Boil for 10 minutes. Sauté the vermicelli in a little olive oil and add the rice, corn, and salt. Stir and serve with the chicken.
