01 - Place the chopped walnuts in a dry skillet over medium heat. Toast for 3 to 4 minutes, stirring frequently, until fragrant and lightly golden. Remove from heat and set aside to cool.
02 - In a large mixing bowl, combine the shaved Brussels sprouts, sliced apple, toasted walnuts, shaved Parmesan cheese, and dried cranberries. Toss gently to distribute evenly.
03 - In a small bowl or jar, whisk together the olive oil, apple cider vinegar, Dijon mustard, honey or maple syrup, minced garlic, salt, and pepper until the dressing is fully emulsified and smooth.
04 - Pour the dressing over the salad ingredients and toss thoroughly to ensure everything is evenly coated.
05 - Allow the salad to rest for 5 to 10 minutes at room temperature so the flavors can develop and the Brussels sprouts soften slightly.
06 - Transfer to serving bowls or plates. Garnish with additional toasted walnuts or extra Parmesan if desired, and serve immediately.
