Miso marinated halibut fillets are a delicious and healthy seafood dish. The halibut fillets are marinated in a flavorful mixture of miso paste, soy sauce, ginger, and garlic, which infuses them with a rich umami flavor. The fillets are then grilled or baked until they are tender and flaky. This dish is perfect for a light and nutritious dinner, and it pairs well with steamed rice and vegetables.
