Preheat the oven to 375 degrees F (190 degrees C). In a small bowl, stir together the sun-dried tomatoes, olives and capers. Set aside.
Place the tilapia fillets side by side in a baking dish. Drizzle with oil and lemon juice.
Bake for 10 to 15 minutes in the preheated oven, until the fish flakes with a fork. Check after 10 minutes, so as not to overcook, or the fish may be dry. When fish is done, top with the tomato mixture, and serve.
