Step 1

Add the tomatoes, jalapeño, onions, cilantro and lime juice to a bowl and mix to combine. Add 2 tablespoons olive oil and season with salt and pepper. Let sit at room temperature for at least an hour for all the flavors to come together.

Step 2

Set up your grill for indirect heat. If using a charcoal grill, build the coals on one side only. If using a gas grill, heat one side only. Drizzle the swordfish with olive oil and sprinkle with salt and pepper on both sides. Place on the direct-heat side of the grill and cook until nicely charred, 2 to 3 minutes per side. Move to the indirect-heat side of the grill, close the lid and cook until cooked through, another 3 to 4 minutes. Remove from the grill to rest, about 5 minutes. Serve the swordfish with the salsa spooned over the top.
