Preheat oven to 450°F. Line baking sheet with parchment paper, or spray lightly with cooking spray.
In a medium bowl, toss butternut squash cubes with 1 ½ tbsp olive oil, salt and pepper.
Spread out on prepared baking sheet. Roast for 35 to 45 minutes, until squash is as tender as desired.
While squash is roasting, heat ½ tbsp olive oil in a small skillet. Add garlic, sage and pine nuts, and sauté until pine nuts are lightly browned. Remove from heat.
Scoop butternut squash into a large bowl. Scrape contents from the skillet onto the butternut squash and gently toss. Serve immediately.
