Preheat oven to 350°F (175°C). Spread almonds or pecans on a baking sheet and toast for 5–7 minutes until fragrant. Let cool, then chop.
In a small bowl, whisk together olive oil, apple cider vinegar, maple syrup, Dijon mustard, garlic powder, salt, and pepper until smooth.
In a large bowl, add chopped kale and drizzle with 1 tsp of the dressing. Gently massage the kale with your hands for 1–2 minutes until it softens slightly.
Add shredded Brussels sprouts, broccolini, dried cherries, and toasted nuts to the kale.
Pour the remaining dressing over the salad and toss well to combine.
Sprinkle with grated Parmesan cheese and serve immediately.
