If salmon is the well-dressed aristocrat of seafood, tuna is the unpredictable double agent: canned, it’s a shoestring budget staple that’s right at home with the value-sized bags of rice and potatoes, but left as a steak, it’s suddenly transformed into a gourmet dinner. This recipe takes advantage of tuna’s sophisticated side, topping medium-rare grilled fish with juicy salsa for an elegant, minimalist dinner.
It’s lucky that tuna and avocado taste so good together, because avocado adds one of the few vital nutrients that tuna is lacking: fat. Other than that, tuna is extremely nutritious, and there’s no reason to be afraid of mercury, since the naturally occurring selenium in fish will protect you from mercury toxicity (read more about this in the article on fish and seafood).
Like most salsas, this one is best if you let it marinate for a few hours beforehand, so the flavors have time to mature. A quick way to do this is to chop up the salsa ingredients while you’re preparing lunch, and then let them chill in the fridge until dinner time. Because the salsa in this recipe brings so much flavor, don’t go crazy spicing the fish. I only used sea salt and black pepper with a pinch of ground coriander. Also make sure you don’t leave it too long on the grill; tuna is so lean that it’s easy to over-cook, and dry, rubbery fish is nobody’s friend. Cooked on the outside but still rare in the middle, it’s perfectly safe to eat, and melt-in-your-mouth tender all the way through.
