• 3 cloves garlic, minced
• 1 (14.5-ounce) can chopped tomatoes (or 2-3 fresh medium tomatoes, chopped)
• 1 bay leaf
• ½ teaspoon salt (or to taste)
• ¼ teaspoon black pepper
• 1 cup long-grain white rice or parboiled rice (see notes for brown rice)
• 2 cups low-sodium chicken or vegetable broth, or water

Directions

1. Prep the Tuna & Make the Marinade
   1. Pat the tuna steaks very dry with paper towels. If you prefer a milder flavor, you can trim any dark bloodline from the center of the steaks.
   2. In a small bowl, whisk together the 2 tablespoons olive oil, lemon/lime juice, minced garlic, minced onion/shallot, bay leaf, black pepper, smoked paprika, and optional fresh chili.
   3. Place the tuna steaks in a shallow dish or zip-top bag and pour the marinade over them, ensuring they are well coated. Let them rest for 15–30 minutes at room temperature while you prepare the rice. If marinating longer, refrigerate for up to an hour, but avoid an extended acid bath to prevent "ceviche-ing" the fish. Remember to wash your hands thoroughly after handling raw fish.
2. Start the Simple Garlic Tomato Rice
   1. In a medium saucepan or Dutch oven, heat 1 tablespoon olive oil over medium heat. Add the chopped onion and sauté until softened, about 5-7 minutes.
   2. Add the minced garlic and cook for another minute until fragrant.
   3. Stir in the chopped tomatoes, bay leaf, salt, and pepper. Cook, stirring occasionally, for 5-7 minutes, breaking down the tomatoes with your spoon, until the mixture thickens slightly. This builds a rich flavor base.
   4. Stir in the rice, coating it thoroughly with the tomato mixture. Cook for 1-2 minutes, stirring, to lightly toast the rice.
   5. Pour in the broth or water. Bring the mixture to a gentle boil, then immediately reduce the heat to low, cover the pot tightly, and simmer for 18-20 minutes for white or parboiled rice (longer for brown rice, typically 40-45 minutes). Do not lift the lid during this time.
   6. Once the rice is tender and the liquid is absorbed, gently fold in the chopped green olives (if using). Remove from heat, keep covered, and let it rest for 5-10 minutes. Then, fluff with a fork. Keep the rice covered on the back burner while you grill the tuna.
3. Grill the Tuna Steaks Perfectly
4. Set up your grill: Preheat your gas or charcoal grill to high heat. Ensure the grates are clean and lightly oiled to prevent sticking.
   1. Remove the tuna steaks from the marinade, shaking off any excess. Discard the used marinade.
   2. Carefully lay the tuna steaks on the hottest part of the grill. For 1–1¼-inch thick steaks, sear for about 1½–3 minutes per side for medium-rare doneness.
5. Don't move them for the first minute or so to allow a nice crust to form. Flip once. You can do a quick second turn after flipping to create crosshatch grill marks, but be mindful not to overcook.
6. Visual cues for doneness: The edges of the tuna will turn opaque, but the center should still be rosy and translucent. You're looking for light grill marks, not a blackened crust.
   1. Once cooked to your liking, transfer the grilled tuna steaks to a warm plate. Loosely tent them with foil and let them rest for 3–5 minutes. This allows the juices to redistribute, ensuring a tender, juicy steak.
7. Plate It Up!
   1. Spoon a generous bed of the garlic tomato rice into shallow bowls or plates.
   2. You can serve the tuna steaks whole or, for an elegant presentation, slice them across the grain into thick pieces.
   3. Garnish with fresh chopped parsley or cilantro, a squeeze of fresh lemon or lime, and a final drizzle of good quality olive oil. Serve immediately.
