I love this fresh, bright, vibrant recipe. It's a simple, but sophisticated salsa. First I rub the tuna with smoky spices, and slap it on the grill just to infuse the taste of char. Then, I dice the rare tuna and toss with diced fresh avocado, tomato, green onion, and cilantro, and bind it together with lime and lemon and olive oil and sea salt. Scoop it up with corn chips.
