The menu for the class chosen by a power couple from NY, USA was:
Sushi roll with seafood, aubergine with sweet Miso sauce, spinach with sesame sauce, and Miso soup with dashi stock.
So except for salmon and Maguro for Sushi, all our ingredients were vegetarian! I cannot say gluten-free because our soy sauce uses some wheat. But no worries I can grab a Tamari-style soy sauce if my guests like no gluten in his/her meal, which uses soybeans only and no wheat.
My guest couple completed a beautiful Sushi lunch and we had a fun talk over our healthy homemade food. Many thanks for coming!
