Red onion and celery add crunch to this quick chicken salad. Blueberries have thick skins, so they won't break apart when tossed with the chicken.
1. Combine first 4 ingredients in a medium bowl; sprinkle with 1/4 teaspoon salt. Combine yogurt, 1 tablespoon lemon juice, and honey in a small bowl, stirring with a whisk. Add yogurt mixture to chicken mixture; toss to coat. Gently stir in blueberries. Place arugula, remaining 1 1/2 tablespoons lemon juice, oil, remaining 1/4 teaspoon salt, and pepper in a bowl; toss to coat. Divide arugula mixture evenly among 6 plates; top each serving with about 3/4 cup chicken mixture.
