Case in point, this delicious tuna recipe that only takes 20 minutes. You'll start by stirring together a flavorful salsa-esque salad made from cherry tomatoes with capers, parsley, and Castelvetranos (a mild, buttery green olive). Next, the tuna gets a short sear, and finally, you'll use that same pan to whisk up a mustardy shallot vinaigrette. P.S. It's worth keeping the salad combination in your back pocket to spoon over grilled chicken breasts, baked tofu, or seared steaks. Ingredients 1 pound cherry tomatoes, halved (about 3 cups) ½ cup pitted Castelvetrano olives, quartered ⅓ cup chopped fresh flat-leaf parsley (from 1 bunch) 2 tablespoons nonpareil capers, drained and chopped, plus 1½ tablespoons caper brine 5 tablespoons olive oil, divided 1 ¼ teaspoons kosher salt, divided ¾ teaspoon freshly ground black pepper, divided 4 7-oz. tuna steaks (about 1 in. thick) 1 shallot, finely chopped (¼ cup) 2 tablespoons sherry vinegar 1 teaspoon whole-grain mustard Directions Stir tomatoes, olives, parsley, capers and brine, 1 tablespoon oil, and ¼ teaspoon each salt and pepper in a bowl until well combined. Let stand at room temperature until tomatoes start to release their juices, about 10 minutes. Meanwhile, heat 1 tablespoon oil in a large cast-iron or nonstick skillet over medium-high until shimmering. Season tuna steaks with remaining 1 teaspoon salt and ½ teaspoon pepper. Add tuna to skillet and cook, flipping once, until desired degree of doneness, 1 to 1½ minutes per side for rare. Transfer to a plate. Reduce heat to medium and add shallot to skillet; cook, stirring constantly, until softened, about 30 seconds. Remove skillet from heat and stir in vinegar, mustard, and remaining 3 tablespoons oil. Cut tuna across the grain into ½-inch-thick slices. Serve tuna with tomato-olive relish. Drizzle with warm shallot vinaigrette.
