Step 1: Prepare the Salad Base
Slice the celery stalks thinly and place them in a large salad bowl. Add the chopped apple and parsley.

Step 2: Add the Crunch
Stir in the sliced almonds and chopped pistachios for texture and flavor.

Step 3: Make the Dressing
In a small bowl, whisk together the lemon juice, minced shallot, honey, and Dijon mustard. Slowly drizzle in the olive oil while whisking until the dressing is smooth and emulsified.

Step 4: Combine the Salad
Pour the dressing over the celery and apple mixture. Toss gently to coat everything evenly.

Step 5: Add the Cheese and Season
Sprinkle the crumbled blue cheese over the salad. Season with salt and freshly ground black pepper to taste.

Step 6: Serve
Toss lightly again and serve immediately for the best crunch and freshness.
