Cook and drain pasta as directed on package, omitting salt.
Meanwhile, rub both sides of beef pieces with coarsely ground pepper. Heat 10-inch nonstick skillet over medium heat. Cook beef in skillet 8 to 12 minutes, turning once, until almost done.
Add remaining ingredients except pasta to skillet. Reduce heat to medium-low. Cook uncovered about 5 minutes or until beef is medium doneness (160ºF). Mix vegetables with pasta; top with beef.
