Grilled Tuna Niçoise

• 4 cups cubed red potato (about 1 1/4 pounds)
• 1/2 pound green beans, trimmed
• 1 (8-ounce) tuna steak (about 3/4 inch thick)
• Cooking spray
• 1/2 cup vertically sliced red onion
• 1/2 cup chopped fresh parsley
• 1 tablespoon chopped fresh or 1 teaspoon dried tarragon
• 1/2 cup fat-free, less-sodium chicken broth
• 3 tablespoons white wine vinegar
• 1 tablespoon extra-virgin olive oil
• 1 tablespoon Dijon mustard
• 1/4 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• 8 cups gourmet salad greens
• 1 cup cherry tomatoes, halved
• 1/4 cup nicoise olives

1. Cook the potato in boiling water for 6 minutes or until tender; remove with a slotted spoon. Add green beans to boiling water, and cook 3 minutes or until crisp-tender. Drain.
2. Prepare grill or broiler.
3. Place the fish on a grill rack or broiler pan coated with cooking spray; cook for 3 minutes on each side or until desired degree of doneness. Cut the fish into 1-inch chunks.
4. Combine potato, fish, onion, parsley, and tarragon in a large bowl. Combine the broth and next 5 ingredients (broth through pepper); stir well with a whisk. Pour 1/2 cup broth mixture over potato mixture, and toss well.
5. Divide beans, greens, and tomatoes evenly among 4 plates. Top each serving with 1 1/2 cups potato mixture and 1 tablespoon olives. Drizzle 1 tablespoon of remaining broth mixture over each serving.
