Combine onion, 1/2 cup wine, sugar, 1 teaspoons thyme and 1/4 teaspoons black pepper in a large Dutch oven. Cover and cook over medium heat 20 minutes or until onion is soft, stirring occasionally. Add vinegar, cook uncovered, 15 minutes or until liquid almost evaporates and onions are caramelized. Remove 3/4 cup onion mixture; set aside.
Sprinkle the veal with 1/4 teaspoons black pepper. Add 1 cup wine, 1 teaspoons thyme, veal, broth, red pepper, tomatoes, and garlic to pan; bring to a boil. Cover and reduce heat and simmer 1 hour and 15 minutes, turning veal occasionally. Uncover and cook for 30 minutes. Stir in pasta and beans and simmer 15 minutes or until pasta is tender. Serve with the reserved onion mixture, basil, and lemon zest.
