Combine sun-dried tomatoes and next 5 ingredients in a food processor. Pulse until finely minced. Set aside.
Place fillets on a lightly greased baking sheet and drizzle with oil. Sprinkle with salt and pepper.
Broil fillets 5 inches from heat 7 to 10 minutes or until opaque. Top with tapenade, and serve immediately.
Note: Rich, velvety sablefish, also known as butterfish or black cod, can be difficult to find in local markets, so buy it when you see a fresh supply. If unavailable, substitute Pacific halibut, cod, wahoo, or another firm white fish.
Wine note: "A French Vouvray or a Pinot Noir," says Eric Fullagar, at Freeport Cheese & Wine in Maine. "Another choice would be a dry French rosé. Most people are perplexed by rosé, but it's food-friendly."
