Combine beef, wine, oil, orange peel, garlic, bay leaf, thyme and pepper in large glass bowl. Refrigerate, covered, at least 2 hours or overnight. (I do mine overnight)
Place beef mixture, mushrooms, and tomatoes in large nonstick skillet or dutch oven. Add enough broth to just cover ingredients. Bring to a boil over high heat. Cover; reduce heat to low. Simmer 1 hour. Add potatoes, carrots and onions; cover and cook 20 to 25 minutes or until vegetables are tender. Remove meat and vegetables from skillet with slotted spoon; cover and set aside. Discard orange peel and bay leaf.
Combine cornstarch and water until blended. Stir into skillet with sauce. Increase heat to medium; cook, stirring until sauce is slightly thickened. Return meat and vegetables to sauce; cook until heated through. Makes 6 servings
