@farmerman,
Here's one I haven't tried (and may not)

Butternut Squash-Stuffed Shells With Rosemary & Walnut Butter
Ingredients:
1 3/4 to 2 pounds butternut squash- peeled, seeded and cut into chunks (about 3 to 4 cups)
2 tablespoons vegetable oil
16 to 24 large pasta shells, depending on the size
1/4 to 1/2 teaspoon finely minced rosemary
3/4 cup whole-milk ricotta
1/3 cup grated pecorino cheese
-- Kosher salt and pepper, to taste
1 stick (4 ounces) unsalted butter
3/4 cup chopped walnuts
1 branch rosemary
Instructions:
Preheat the oven to 400 degrees. Toss the squash with the oil, then roast until golden and tender, about 45 minutes. Meanwhile, cook pasta shells according to package instructions; drain and set aside.
Remove the squash from the oven, and reduce the heat to 325 degrees. Place the squash and minced rosemary in the bowl of a food processor fitted with the steel knife, and puree until smooth. Transfer to a mixing bowl, add ricotta and pecorino, and season with salt and pepper.
Spoon about 1 1/2 tablespoons of the squash mixture into each shell. Arrange the shells in a single layer in a shallow baking dish. Cover with foil, and place in the oven to keep warm.
Melt the butter in a medium saute pan over medium-high heat. Add the walnuts and rosemary, and cook for 3 to 5 minutes, until butter browns lightly and walnuts smell toasty. Remove from heat, discard rosemary, and season with salt and pepper.
Spoon lightly over squash stuffed-shells. Serve immediately.
