5. In a large mixing bowl, combine cooked pasta, roasted roots, and sauce. Mix well to coat evenly.
6. Transfer everything to a greased baking dish (about 9×13 inches). Top with vegan cheese or bread crumbs if you like.
7. Bake uncovered for 25-30 minutes until bubbling around the edges and the top is golden brown.
8. Finish with a sprinkle of fresh herbs or a squeeze of lemon for brightness.
