Cut meat into 1 inch cubes. Heat the oil in a large skillet. Place flour into a large plastic bag, and toss the meat in the flour to coat evenly. Fry in the oil until the outside is browned. Does not need to be fully cooked.
Transfer to 5 qt. slow cooker, and stir in broth, onions, tomatoes, wine and seasonings. Cover and cook on low 7—8 hours. During last 30 minutes, stir in the raisins.
Serving suggestions: Over couscous, add chickpeas, naan bread on the side.
