                    I loved this flavorful soup when my sister made it and had to have the recipe. I think she got it the recipe from  The Big Book of Soups and Stews  . I am posting it here for safekeeping. Ingredients: 
                    
                        
                                                1 tablespoon vegetable oil  |  
                                                1 lb round steak, cut into 1 inch cubes  |  
                                                1 tablespoon butter or 1 tablespoon margarine  |  
                                                3 medium yellow onions, sliced into rings  |  
                                                6 cups beef stock or 6 cups broth  |  
                                                1 tablespoon dijon mustard  |  
                                                1/4 cup dry red wine  |  
                                                1 teaspoon salt  |  
                                                1/2 teaspoon freshly ground pepper, to taste  |  
                                                6 ounces medium mushrooms, sliced  |  
                                                1/4 cup chopped parsley  |  
                                                1 cup grated swiss cheese, for topping  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. In a large dutch oven over medium high heat, warm oil. 2. Add beef cubes and brown, about 3 minutes. Remove to a plate. 3. Reduce heat to medium-low.

Reduce heat to medium-low and simmer, covered, until meat is very tender, about 1 hour. 6. Add mushrooms and simmer 30 minutes longer. Add parsley. 7. Ladle into bowls and sprinkle with cheese.                              |
