Cook pasta according to package directions, omitting salt and fat.
While pasta cooks, heat a large nonstick skillet over medium-high heat. Add the beef; cook until browned, stirring to crumble. Drain beef, and set aside.
Add onion and garlic to pan; sauté 3 minutes. Add wine; cook 3 minutes or until liquid almost evaporates.
Stir in beef and spaghetti sauce; bring to a boil. Reduce heat, and simmer 5 minutes, stirring occasionally. Stir in the milk, salt, and pepper; cook 3 minutes, stirring occasionally. Serve sauce over pasta.
