For the salsa: Combine all the vegetables in a bowl. Chop cilantro finely. Mix rice wine vinegar, sugar, salt, lime juice, and fish sauce together until well blended. Add all chopped vegetables and cilantro to the mixture. Mix well.
For the halibut: Season with sea salt and pepper. Place the halibut directly onto a hot grill for a few minnutes. Then using tongs or a spatula give the halibut a quarter turn to create the second set of marks resulting in a crisscross pattern. When it's time to flip it, repeat the process of grilling for a few minutes and then give it a quarter turn. Remove from grill and finish in the oven.
Assembly: Spoon a nice mound of salsa in the center of each plate, adding a bit of the salsa juice. Place the halibut fillet on top. Garnish with chili threads and microgreens. Add chili oil to edges of salsa for color and heat. Enjoy!
