Preheat a cast iron pan to medium heat. Season tuna with salt and pepper. Drizzle some olive oil over tuna then add the ginger, garlic, soy sauce, and sugar. Gently incorporate the ingredients. When the pan starts to smoke, sear the tuna about 2 minutes per side depending on how you like it. Transfer to a platter. In a medium bowl, combine the tomatoes, onion, cilantro, jalapeno, lime juice and season with salt and pepper. Serve tuna with the salsa. Yum!
