I make it! I've made it for years.
I have a Japanese book on sushi making; they use things like Vienna sausages and spam.........
I found 'cider vinegar' gives a fruitier fresher spark to the sushi rice.
So after experimenting I found smoked ham, beef, mozzarella cheese, sliced pickles, pineapple work very well in sushi roll also.
I make rednek hillbilly sushi for squeamish newbies; usually with ham or beef, green onion, cream cheese, pickle, & pickled ginger and they seem to love it.
You probably know to keep dipping the very sharp knife in a glass of water so it will cut easier. I use a wet fine serrated knife to cut through the nori.
I buy the wasabi in the tube rather than the powder; it is 'spicier' and stays fresh.
Have fun experimenting American style....
