Preheat the oven to 350 degrees. Heat the oil in an ovenproof casserole and brown the meat well on all sides. Season with salt and pepper.
Stir in the apple, onion, tomato and tomato paste. Cook a minute, then pour in the wine and adjust the seasoning. Bring to a boil, cover, and transfer to the oven.
Cook for 1 ½ hours, adding chicken broth or water if the liquid cooks away.
