Creating Butternut Squash Tortellini can be a fun project that results in a delightful meal. Follow these simple steps to make your own tortellini:

1. Prepare the Squash: Preheat your oven to 400°F (200°C). Toss the diced butternut squash with olive oil, salt, nutmeg, and pepper. Spread it on a baking sheet and roast for about 25 minutes or until tender.
2. Make the Filling: Once roasted, mash the butternut squash in a bowl. Stir in Parmesan cheese and fresh sage, mixing until smooth. Set aside to cool.
3. Prepare the Dough: In a large bowl, combine flour and salt. Make a well in the center and crack in the eggs. Mix until a rough dough forms. Knead on a floured surface for about 5-7 minutes until smooth.
4. Roll Out the Dough: Divide the dough into quarters. Roll out one quarter at a time to about 1/16 inch thickness, keeping the rest covered to prevent drying.
5. Cut the Dough: Use a round cutter (about 3 inches in diameter) to cut circles from the rolled-out dough.
6. Fill the Tortellini: Place about 1 teaspoon of filling in the center of each circle. Fold the dough over to create a half-moon shape. Pinch the edges to seal tightly, then bring the two ends together to form the tortellini shape.
7. Cook the Tortellini: Bring a large pot of salted water to a boil. Carefully drop the tortellini in batches, cooking for 2-3 minutes or until they float to the surface. Remove with a slotted spoon.
8. Prepare the Sauce (optional): In a skillet, combine heavy cream and additional Parmesan cheese over medium heat. Stir until smooth, adding cooked tortellini to the sauce and tossing to coat.
9. Serve: Plate your Butternut Squash Tortellini, drizzling with sauce and topping with more Parmesan and sage if desired.

With these steps, you will create a beautiful dish that is sure to impress.
