These Flash-Fried Nori and Tuna Rolls are out of this world with their crisp panko-tempura exterior and soft tender interior of fresh tuna. Yum! Experiment with other fillings too. The Ginger-Wasabi Butter Sauce is a great match for this dish, with its French origins and Japanese flavors. The creaminess of the sauce balances with the heat of the wasabi and perfectly compliments the crispy roll.
