Autumn Harvest Baked Casserole

Autumn Harvest Baked Casserole layers tender roasted butternut squash and sweet potatoes with nutty whole-grain couscous, juicy apple chicken sausage, and melty mozzarella. The result is a cozy, lightly sweet and savory bake with pops of bell pepper and green onion for freshness. Ideal for Thanksgiving or any cool-weather dinner, and easy to adapt by skipping the sausage for a satisfying vegetarian option.
