Step 1

To make a lemon-dill dressing, in a medium bowl, combine mayonnaise, 3 tablespoons lemonade concentrate, dill, and salt; mix well, cover and chill.

Step 2

In a large skillet, bring remaining lemonade concentrate and water to a boil over medium heat. Add catfish, reduce heat to low; cover and cook 7 to 8 minutes, or until fish is firm in center and flakes easily with a fork. Remove from skillet to a plate and allow to cool. If not serving immediately, cover and refrigerate until ready to serve.

Step 3

To make salad, evenly divide salad greens, tomatoes, cucumber, red onion, green beans (if desired), and roasted potatoes (if desired) into serving bowls. Top with catfish and a spoonful of lemon-dill dressing. Sprinkle with coarse pepper and serve.
