1. Heat the vegetable oil in a deep saucepan, add the wild rice, water and MAGGI® chicken bouillon, cover and simmer on medium heat until rice is ¾ cooked.
3. Stuff the cavity of the fish with the filling and tie shut using kitchen string.
4. Place onion rings on the bottom of a deep ovenproof dish, drizzle with the olive oil and place fish over the onions so the fish does not directly touch the pan.
5. Bake the fish in a preheated oven for 40 minutes at 200°C.
