                    While the soup simmers, Jo assembles tasty Mozzarella Tuna Melts.  Our daughter's home economics teacher shared the recipe for these all-American favorites,  she notes. Using a mini food processor to chop the celery and onion for the filling helps shave preparation time. Then Jo just pops the sandwiches in the oven. Ingredients: 
                    
                        
                                                1 can (6 ounces) water-packed tuna, drained and flaked  |  
                                                1/4 cup finely chopped celery  |  
                                                1/4 cup finely chopped onion  |  
                                                1/4 cup fat-free mayonnaise  |  
                                                4 hamburger buns, split  |  
                                                4 slices part-skim mozzarella cheese  |  
                                                4 tomato slices  |  
                                                4 lettuce leaves  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. In a small bowl, combine the tuna, celery, onion and mayonnaise. Spread on bottom of buns; set bun tops aside. Top tuna mixture with a slice of cheese and tomato. 2. Place on an ungreased baking sheet. Bake, uncovered, at 350° for 12-15 minutes or until heated through and cheese is melted. Top each with a lettuce leaf; replace bun tops. Yield: 4 servings.                              |
