Here's a salad that's as beautiful as it is delicious. The spicy orange-ginger dressing is so good, you'll want to double (or triple) it to serve on your salad throughout the week.

  • Ready In

  1. Preheat grill to medium-high heat.
  2. Combine orange juice, soy sauce, sesame oil, ginger, hot sauce and 1/8 teaspoon pepper in a large bowl. Transfer half the dressing to a small bowl; add scallions, water chestnuts and sesame seeds, and toss.
  3. Rub tuna with canola oil and sprinkle with salt and the remaining 1/8 teaspoon pepper. Grill until the fish is opaque, 4 to 5 minutes per side.
  4. Add watercress to the large bowl and toss to coat with the remaining dressing. Cut the tuna into 2 portions. Divide the watercress between 2 plates and top with the tuna and scallion-ginger relish.
  • Make Ahead Tip: Prepare through Step 2, cover and refrigerate for up to 6 hours.
  • Tips for Two: Store leftover water chestnuts in the refrigerator, covered with water; they keep for up to 1 month with daily water changes. Add to a stir-fry; toss in a green salad; jazz up chicken or tuna salad; Asian Brown Rice.
  • Tip: To toast sesame seeds, heat a small dry skillet over low heat. Add sesame seeds and stir constantly until golden and fragrant, about 2 minutes. Transfer to a small bowl and let cool.

Question: My husband commutes so is it possible for me to substitute the tuna steak with canned tuna to save money and time?

This was good. I don't know if I cooked the fish too long but it was a little dry and chewy. Despite that I still gave it four stars. I used the "relish" or sauce to pour over the fish and it gave it a nice flavor.
