Marinate the red snapper or halibut the day before in the traditional Caribbean Green Seasoning Marinade.
Heat either a large heavy frying pan (cast-iron is awesome, but I use LeCruset), or heat up your grill to a medium-high heat
Before serving time, sauté the marinated fish in a skillet for about 3 - 4 minutes on each side in 2 - 3 Tbsp. of olive oil until nicely golden brown and cooked through. If grilling, do exactly the same process.
Slightly warm and soften the tortillas in the microwave for about 25 seconds each. If grilling out, briefly place them on the outside of a hot grill for a few seconds to warm them up. Keep a good eye on these to remove quickly and avoid burning.
Chop, slice, and prepare all of the toppings for the tacos.
Prepare chipotle, cilantro and lime crema simply by combining all of the ingredients.
When fish is finished cooking/grilling, cut each filet into 1/2" cubes. The fish should easily flake apart.
Serve the fish tacos either completely assembled as shown in the photos OR present toppings and the crema in separate attractive serving bowls and allow guests to prepare their own fish taco and toppings according to their preferences.
