Mix the beef broth, the first measure of olive oil, the vinegar, Worcestershire sauce, cornstarch, sugar, red pepper, basil, marjoram and garlic in a shallow glass baking dish. Add the beef. Stir to coat thoroughly. Cover. Refrigerate 2 or 3 hours, stirring occasionally. Drain the beef. Reserve the marinade. Heat a large, heavy skillet over low heat. Add the second measure of oil. Saute the onion and green bell pepper until tender (3-4 minutes), stirring constantly. Stir in the beef. Increase the heat to medium. Saute until the beef is brown (about 3 minutes), stirring constantly. Stir in the reserved marinade. Cook until the sauce thickens (1-2 minutes), stirring frequently. Serve over hot, buttered noodles.
