Combine all ingredients, except swordfish, in a bowl and mix together well. Set aside.
Preheat a grill to medium-high, using mesquite wood. Place swordfish on grill and quickly sear. Dredge swordfish in the white wine mixture and then return to the grill. Cook until desired doneness; fish should be opaque and a knife should slide in easily.
Remove fish from the heat and serve with fresh vegetables and a starch of choice.
