1. Rinse fish slices and place in a large ziplock bag. Combine coconut milk and lime juice and pour over fish slices. Marinate overnight in the refrigerator or for at least one hour on your counter.
2. Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius). Measure one and a half cups coconut flakes into a 9×13-inch baking pan. Toast coconut flakes for 10 minutes until golden. Remove from oven and mix well.
3. Mix dressing ingredients together until smooth. Place 1/2 of the dressing in a small bowl, reserving the rest to serve with the cooked fish.
4. Place the toasted coconut next to the bowl with the dressing. Remove fish from marinade and pat dry. Coat each piece of fish evenly with dressing and then dredge in the toasted coconut. Place on a baking sheet lined with Gefen Parchment Paper and sprayed with cooking spray. Repeat with remaining pieces of fish. Bake for 20 minutes uncovered. Remove from oven and allow to cool.
Serve each portion with a tablespoon of reserved dressing.
