Season the beef with black pepper. Wrap the bacon around the meat. Heat the oil in a large pan. Sauté the beef, until lightly coloured. Place to one side.
Sauté the onion, until softened. Add the garlic then tip the mixture into the cooker. Place two sprigs of rosemary on top then add the meat. Top with the remaining rosemary, the stock, balsamic vinegar and tomatoes.
Cover and cook on low for 8 hours. Remove the meat to a carving platter. The sauce can be thickened with a little flour, if preferred. Serves 6. |
