Preparing this salad is no trouble at all, but if you want it easier than easy, or you just don't like medium-rare fish, use canned tuna instead of the fresh steaks.
Substitute two six-ounce cans of drained canned tuna for the fresh tuna. Skip Step 1 completely and add the drained canned tuna along with the lettuce and radishes.
Pinot Noir works beautifully with meaty fish such as salmon, swordfish, and especially tuna. For this salad, pour one of the many excellent examples from Oregon, where Pinot Noirs have bright raspberry flavors and a refreshing, lively crispness.
