Put all the spices, garlic, scallions, peppers, lime juice, salt, to taste, and a dash of soy sauce in a blender. Combine ingredients with oil to make a paste. Score the fish, and then rub the marinade into the fish. Place in a resealable plastic bag and refrigerate for 30 minutes. Remove the snapper from the bag and place on a greased grill, cooking each side for 7 minutes without flipping.
While the fish is cooking, brush the zucchini with oil, and season with salt and pepper. Put zucchini slices and whole bell peppers on grill, cooking until the zucchini is tender and red pepper blackened. Set zucchini aside and let the red pepper steam in a covered bowl for a few minutes before removing the skins. Serve vegetables with the whole fish, garnished with Island Salsa.
Combine the chopped the fruit and onion in a bowl. Stir in the red wine vinegar and cilantro. Then add salt and pepper, to taste. The salsa will be served on the side to cool off the spice of the fish.
