Trim fat from beef; cut beef into 1-inch cubes. Coat a large nonstick skillet with cooking spray; place over medium-high heat until hot. Add beef and onion; saute 5 minutes. Combine flour, salt, and pepper; sprinkle over beef mixture, and cook 1 minute, stirring constantly. Add mushrooms and next 7 ingredients (mushrooms through tomatoes); bring to a boil. Reduce heat, and simmer, uncovered, 40 minutes or until beef is tender, stirring occasionally. Garnish with parsley, if desired.
Note: Substitute 1 cup chicken broth for the 1 cup vermouth, if desired.
