1. Place the orange juice, wine, blacken, and grouper in a Teflon lined fry pan, Place a lid on it and bring it to a boil. Poach the grouper for about 10 minutes, then flip it over and continue cooking until it's tender (5 - 10 minutes longer. Remove and let cool.
2. Mix the dressing in a bowl large enough to hold the finished product. Cut the grouper into 1/2" - 3/4" pieces and add to the dressing. Toss gently to combine all of the ingredients, and add a little more mayonnaise if needed, but just enough to hold it all together. You toss is gently so that you don't break up the pieces of grouper.
3. This is really best if you make it a day ahead of time, and store in it the refrigerator. This extra time will let the flavors blend together better.
Drizzle with fresh lime juice just before serving, to bring out the flavors.
