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.

2 servings | Active Time: 45 minutes | Total Time: 45 minutes

Ingredients

• 2 tablespoons orange juice
• 1 tablespoon reduced-sodium soy sauce
• 1 tablespoon toasted sesame oil
• 1 teaspoon minced fresh ginger
• 1/2 teaspoon hot sauce
• 1/4 teaspoon freshly ground pepper, divided
• 1/2 cup thinly sliced scallions
• 1/2 cup drained, canned water chestnuts, diced (see Tips for Two)
• 1 tablespoon sesame seeds, toasted (see Tip)
• 1 8-ounce tuna steak, about 1-inch thick
• 1/2 teaspoon canola oil
• 1/8 teaspoon salt
• 4 cups watercress, washed and trimmed (about 1 bunch)

Preparation

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.

Tips & Notes

• 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.
