Barbecued or baked stuffed acorn squash is a delicious and hearty dish that combines the sweetness of acorn squash with savory fillings. The squash is halved and roasted until tender, then filled with a mixture of cooked grains, vegetables, and protein. It is then topped with barbecue sauce and baked until the flavors meld together. This dish is perfect for a vegetarian main course or a side dish for a barbecue or holiday meal.
