Cut the squash in half lengthwise and scoop out the seeds. Place squash cut side down on a baking sheet lined with parchment paper.
Bake for 25 minutes, or until squash is tender.
While the squash is baking, heat olive oil in a small skillet over medium heat. Add pine nuts and garlic and cook, stirring, until the pine nuts are golden brown. Stir in sage and remove from heat.
When the squash is done baking, use a fork to scrape out the spaghetti-like strands. Place squash in a bowl and add the pine nut mixture, Romano cheese, salt, and pepper. Toss until well combined.
Serve warm.
