Ingredients

  • 4 (6-ounce) tilapia fillets
  • 1 tablespoon olive oil
  • 1/2 cup chopped fresh tomatoes
  • 5 pitted Kalamata olives, chopped
  • 1 tablespoon finely chopped onion
  • 1 tablespoon capers
  • Salt and freshly ground black pepper, to taste

Directions

  1. Preheat your grill or oven to 400°F (200°C). If using a grill, lightly oil the grates to prevent sticking.
  2. Pat the tilapia fillets dry with paper towels, then brush both sides with olive oil. Season with salt and black pepper.
  3. Grill the tilapia for 3 to 4 minutes per side, or until the fish is opaque and flakes easily with a fork.
    Oven Method: Place fillets on a baking sheet and bake for 10 to 15 minutes.
  4. While the fish cooks, prepare the tapenade. In a small saucepan over medium heat, combine chopped tomatoes, Kalamata olives, onion, and capers.
  5. Cook for 5 to 10 minutes, stirring occasionally, until the tomatoes soften and the mixture becomes fragrant and well blended.
  6. Spoon the warm tomato-olive tapenade generously over each tilapia fillet before serving.
