In a large mixing bowl, combine the shredded carrots, crumbled feta cheese, chopped pistachios, and chopped parsley.
In a separate small bowl, whisk together the olive oil, apple cider vinegar, honey, salt, and black pepper until well combined.
Pour the dressing over the carrot mixture and toss gently to combine, ensuring everything is evenly coated.
Let the salad sit for about 10 minutes to allow the flavors to meld.
Serve immediately or refrigerate for up to 1 hour before serving for a chilled option.
