These halibut tacos are a fresh and flavorful way to enjoy the fish. The halibut is seasoned with a blend of spices and grilled until cooked through. A creamy avocado crema is made by blending avocado, sour cream, lime juice, and cilantro. The grilled halibut is then served in warm tortillas with the avocado crema, shredded cabbage, and diced tomatoes.
