Hi @dreemsteem!
This is great, and certainly very flavorful. I've never liked sushi, not even when I wasn't vegan, I got to try it half way once and it grossed me out, I really don't know how people eat raw fish sushi, I don't understand it.
But your recipe is great. Your son is right, because this is an improvised gourmet recipe, which you put together with few ingredients.
I welcome you to the community, and I invite you to read our community rules. Greetings.
