Prepare the Dressing
In a small mixing bowl, combine the mayonnaise, lemon juice, honey, salt, and black pepper. Whisk until smooth and fully blended.
Assemble the Salad
Place the diced apples, halved grapes, sliced celery, toasted nuts, and chopped parsley in a large bowl. Gently toss to mix the ingredients evenly.
Combine and Serve
Pour the prepared dressing over the salad mixture and toss thoroughly to ensure all components are evenly coated. Transfer to a serving dish, garnishing with parsley and celery leaves, if desired. Add a final sprinkle of black pepper for a finishing touch.
Tip
To toast the nuts, preheat your oven to 350°F. Spread the walnuts or pecans evenly on a baking sheet and bake for 8 to 10 minutes, until golden brown and aromatic. Allow them to cool before chopping.
This classic dish is best served chilled and can be stored in the refrigerator, covered, for up to 24 hours.
