Make the Dressing: In a small bowl or mason jar, whisk together the maple syrup, apple cider vinegar, and Dijon mustard. Slowly add the olive oil, whisking until the dressing is emulsified. Season with salt and pepper to taste.
Assemble the Salad: In a large bowl, combine the mixed greens, apple slices, cranberries, and red onion (if using). Toss gently to combine.
Add Toppings: Sprinkle the goat cheese and toasted nuts over the salad.
Drizzle and Serve: Just before serving, drizzle the maple vinaigrette over the salad and toss gently to coat. Serve immediately and enjoy!
