Whisk dressing ingredients together in a small bowl until smooth.
Combine the salad ingredients in a large bowl. Scrape every bit of dressing over the top and toss well. Taste and adjust to preference. For a creamier salad, stir in a little extra mayo and sour cream until it’s just right.
Enjoy! Serve in sandwiches, on sliced apples, in lettuce boats, or with crackers.
Notes
Note 1: Grab dry-roasted, lightly salted walnuts or quickly roast your own. Spread walnuts in an even layer on a sheet pan and bake at 350°F for 6 to 8 minutes, stirring once halfway through, until lightly toasted and fragrant.Note 2: To keep apples from browning, soak diced apples in a bowl with 2 cups room-temperature water and 1 teaspoon salt for 5 to 10 minutes. Drain, rinse with cold water, shake off excess moisture, and pat dry before adding.Note 3: Serve straight from the bowl, spoon onto mini butter croissants with lettuce, pile onto toasted bread, or enjoy with crackers, pita chips, or veggies.Storage: Best enjoyed the same day. If making ahead, keep the dressing separate and stir together before serving.
