In Dutch oven or large saucepan, heat oil and brown beef. Add tomatoes, onion soup mix and paprika. Simmer covered, stirring occasionally for 1 - 1 1/2 hours or until beef is tender. Stir in flour and salt blended with water. Bring to a boil, then simmer, stirring constantly, until sauce is thickened, about 5 minutes.
Meanwhile, cook noodles according to package directions. To serve, arrange goulash on noodles. Makes about 6 servings.
