In a large salad bowl, combine the spinach, pomegranate arils, feta cheese and chopped nuts.
In a separate small bowl, whisk together the balsamic vinegar, olive oil, Dijon mustard, honey, salt, and pepper to create the dressing.
Drizzle the dressing over the salad and gently toss everything together until well coated.
Taste and adjust seasoning if needed.
Serve and enjoy!
