Chicken, melon, walnuts and feta top mixed salad greens for a refreshing summer salad. Use your favorite summer fruit in place of the melon if you wish.
1/4 cup crumbled feta cheese
Whisk sour cream, vinegar, sugar, poppy seeds, salt and pepper in a large bowl until smooth. Reserve 1/4 cup of the dressing in a small bowl. Add the mixed greens to the large bowl and toss to coat. Divide among 4 plates and top with chicken, melon, walnuts and feta. Drizzle each portion with 1 tablespoon of the reserved dressing.
