Grilled Tuna with Seaweed Salad

Even a dish as simple as grilled tuna can get out of hand if the sauces and sides are calorically wacky. In this recipe, most of the minimal fat comes from the tuna—and the rest is from toasted sesame oil, which provides a lot of flavor. The ingredient that I really love here is the furikake, a Japanese rice seasoning made with bonito flakes, nori flakes, and other seasonings like sesame seeds, dried anchovies, or bits of egg—the sky is the limit. It can be found, along with prepared seaweed salad, at most Asian markets.
