Begin by preheating your oven to 375°F (190°C).
In a mixing bowl, combine breadcrumbs, pine nuts, raisins, parsley, and minced garlic. Drizzle with a tablespoon of olive oil, and season with salt and pepper. Mix until the filling is well combined.
Lay out the swordfish steaks on a clean surface. Spoon the breadcrumb mixture onto each steak, then roll them up tightly and secure with toothpicks.
Heat the remaining olive oil in a large ovenproof skillet over medium heat. Add the swordfish rolls and sear until golden on all sides, about 2-3 minutes per side.
Remove the swordfish rolls from the skillet and set aside. In the same skillet, add the chopped olives and capers, sautéing for a minute.
Pour in the white wine and fish stock, scraping the bottom of the pan to release any browned bits. Bring the sauce to a simmer.
Return the swordfish rolls to the skillet with the sauce. Drizzle with a bit more olive oil.
Transfer the skillet to the preheated oven and bake for about 10 minutes, or until the fish is cooked through.
Serve the swordfish rolls hot, drizzled with the caper and olive sauce, accompanied by lemon wedges.
