                        Kadoya roasted sesame oil 1 tablespoon

                        Chicken stock soup 600ml

                        Salt and pepper Appropriate amounts

Directions
- 
                    Slice onions into thin strips. 
- 
                    Heat Pure Sesame Oil on a pan, put the onions in the oil and saute until the onions turn golden brown, being careful not to let them burn. 
- 
                    Add the chicken stock soup to the pan and simmer for 20 minutes. Add salt and pepper to adjust the taste. 
- 
                    Put the soup into the necessary number of heat-resistant bowls or cups. Put the light-toasted French bread on top. Add a generous sprinkling of grated cheese on top. Put it in an oven preheated at 250 degrees C (500 degrees F) to bake until top browns and bubbly. 
- 
                    Sprinkle with a dash of Pure Sesame Oil (not in the list of ingredients) last. 
Tips: Sesame oil adds richness to onions. While it usually takes 40 minutes to saute onions until golden brown, heating onions in a microwave in advance shortens the time.
