Set out taco ingredients for everyone to make their own or assemble tacos. Add 3 ounces of fish to each grilled tortilla, add the slaw. Lightly splash a little extra pineapple vinegar and salt on the slaw. Garnish with scallion, cilantro, avocado, radish, pickled jalapeño, chili threads, extra crema mixture, and hot sriracha sauce.
