Preheat oven to 400°F and line two baking sheets with parchment paper.
In a medium-sized bowl, toss the butternut squash together with 1 teaspoon of oil, ½ teaspoon of salt, and pepper.
Arrange the squash in a single layer on a baking sheet and roast in the oven for 25-30 minutes, or until it’s tender and has browned around the edges. Flip the pieces at about the halfway point. Remove the baking sheet, and lower the oven to 300°.
In the same bowl, toss the pecans with the remaining oil, the remaining salt, garlic powder, and mustard powder.
Arrange the pecans on a baking sheet and bake at 300° for 8-10 minutes, stirring the nuts at the halfway point. Be sure to keep an eye on them, because they could burn quickly!
Mix all of the dressing ingredients together in a high-speed blender or food processor until smooth and creamy.
Place the kale in a large bowl and pour on half of the dressing. Massage the dressing into the kale until the kale begins to soften. Don’t over-massage it, or it will become too mushy.
Toss in the pecans, pomegranate seeds, and roasted squash. Drizzle on the remaining dressing.
