Cut the rabbit in pieces. Place in a bowl, sprinkle with vinegar and let soak for about 2 hours. Heat the olive oil. Wipe the rabbit pieces dry, then fry and put in a stewing pot. Add the tomato paste or tomatoes, strained through a colander, the vinegar cloves of one whole garlic bulb, the bay leaves, rosemary, salt, pepper, 2 cups of water and the frying pan oil. Let the meal cook for about 45 minutes. In the remaining oil, fry the onions, already peeled and washed, then pour them into the stewing rabbit. Cover the pot and let the meal cook slowly until only very little sauce remains.
Note: Everything can be put in the pot without first frying them. That is, the pieces of rabbit, onions, tomato paste, water, garlic, bay leaves rosemary, salt and pepper. Cover the pot and let the meal slowly cook.
