How to Make It
Combine first 3 ingredients in a shallow dish, stirring until sea salt and sugar dissolve; add fish. Let stand 20 minutes. Drain; pat dry.
Prepare charcoal fire in a chimney starter; let coals burn for 15 to 20 minutes or until flames die down. Carefully pour hot coals out of starter, and pile them onto one side of the grill. Coat grill grate with cooking spray; put grate in place over coals.
Sprinkle 1/8 teaspoon table salt evenly over fish. Lightly coat fish with cooking spray. Place fish, skin side down, over direct heat on grill rack coated with cooking spray; grill 2 minutes or until well marked. Turn fish over and move to indirect heat; grill 12 minutes or until desired degree of doneness.
Heat a small skillet over medium heat; add bacon to pan. Cook 5 minutes or until bacon is almost crisp, stirring occasionally. Add garlic; cook for 2 minutes, stirring frequently. Add paprika, and cook for 20 seconds, stirring constantly. Add tomatoes, and cook for 3 minutes. Stir in butter. Remove from heat. Place 1 fillet on each of 4 plates; top each serving with about 2 tablespoons tomato mixture.
