Description
For such a rich fish, tuna is a good team player—it takes well to all kinds of seasoning. Here, I give it some tang by marinating it with lemon juice and zest, onions, capers, rosemary, and the most surprising ingredient: some of the juice from the caper jar. Have fun playing around with the herbs in the salad; just make sure not to toss them with the dressing until you're ready to serve—tender leaves wilt quickly.
