Preheat the oven to 400 degrees F. Place the butternut squash on a large baking sheet. Drizzle with olive oil and toss. Season with salt and black pepper, to taste. Roast the squash for 25-30 minutes, stirring once, or until the squash is tender. Remove from the oven and set aside.
Place the kale in a large bowl and sprinkle with sea salt. Massage the leaves for for 2-3 minutes, or until they soften and start to wilt. Stir in the chopped brussels sprouts, butternut squash, pomegranate seeds, candied pecans, and Parmesan cheese.
To make the dressing, whisk together the olive oil, apple cider vinegar, mustard, garlic, and shallot. Season with salt and black pepper, to taste.
Pour the dressing over the salad and toss well. Serve!
