Cut the rabbit into eight pieces, wash and pat dry. Rub with salt and pepper. Heat the oil in a roasting pan and fry the meat in it. Add rosemary. Deglaze with wine and 1/4 litre water.
Braise in the preheated oven (electric cooker: 200 °C/ gas: level 3) for one hour. Peel and slice the onion. Clean, wash and cut the peppers into large pieces. Wash, clean and quarter the tomatoes.
Add everything to the rabbit 30 minutes before the end of the cooking time. Season to taste with salt and pepper. Serve garnished with rosemary.
