In a large sauté pan, over medium heat, melt one tablespoon of the butter. Add the shallots and sauté for 1 minute. Add the squash puree and cook until the mixture is slightly dry, about 2 to 3 minutes. Season with salt and pepper. Stir in the cream and continue to cook for 2 minutes. Remove from the heat and stir in the cheese and nutmeg, to taste. Season with salt and pepper. Cool completely.
Cut the pasta ribbon into 3 inch squares. Place 2 teaspoons of the filling in the center of each pasta square. Bring one corner of the square to the other, forming a triangle and seal the pasta completely. Bring a pot, with an insert, of salted water to a boil. Add the pasta and cook until al dente, about 2 to 3 minutes or until the pasta floats and is pale in color.
Remove the pasta from the water and drain well. Season the pasta with salt and pepper.
In a large sauté pan, melt the remaining 8 tablespoons of butter.
Add the sage to the butter and continue to cook until the butter starts to brown. Remove from the heat.
Place some of the pasta in the center of each serving plate. Spoon the butter sauce over the pasta. Grate some of the cheese over each plate and garnish with parsley.
