In a small bowl, whisk together olive oil, apple cider vinegar, honey, salt, and black pepper. Set aside.
Core and thinly slice the Honeycrisp apples. Optional: toss with lemon juice to prevent browning.
Add mixed greens to a large salad bowl.
Top greens with sliced apples.
Sprinkle over feta cheese, walnuts (if using), cranberries, and red onion.
Drizzle dressing over the salad and toss gently to coat.
Optional: Chill for 15 minutes before serving for enhanced flavor.
Serve immediately or store components separately until ready to eat.
Notes
To keep apples from browning, toss in lemon juice before adding to the salad.
Try goat cheese instead of feta for a creamier twist.
Great with grilled chicken or alongside soup for a light dinner.
