Prep the kale by removing the tough center stems and tearing or chopping the leaves into bite-sized pieces. Rinse thoroughly and dry well, preferably using a salad spinner.
Place the kale in a large bowl and drizzle with olive oil and lemon juice. Add the kosher salt. Using clean hands, massage the kale for 2-3 minutes until it begins to soften and turn a deeper green color.
Drizzle the massaged kale with honey mustard dressing and toss until all leaves are lightly coated.
Add the sliced grilled chicken, arranging it evenly throughout the salad.
Distribute the thinly sliced apple pieces throughout the salad.
Sprinkle the toasted almonds over the salad.
Add the shredded parmesan cheese, distributing it evenly throughout the salad.
Season with freshly ground black pepper and gently toss all ingredients together.
Serve immediately for maximum freshness, or chill for 10 minutes to allow the flavors to meld together.
