Begin by washing and drying the Honeycrisp apples, then core and dice them into bite-sized pieces, ensuring the vibrant skin remains intact for color.

In a medium bowl, whisk together the honey, Dijon mustard, and olive oil until fully emulsified. Season with salt and pepper to taste.

In a large mixing bowl, add the diced Honeycrisp apples, crumbled feta cheese, and chopped mixed nuts. Gently fold these ingredients together.

Pour the prepared honey mustard vinaigrette over the mixture and toss gently to coat every ingredient evenly.

Transfer the finished salad to a serving platter or individual bowls. Serve immediately or refrigerate if preparing in advance.
