I actually made this tonight for dinner along with a spinach salad it was healthy, hearty and very comforting!
I love the shape of acorn squash with those scalloped edges, just cut it in half, scoop out the seeds and pulp then roast it in your oven at 375 degrees cut side down for around 40 minutes, after it cools a bit then take a spoon and scoop out some of the meaty flesh along the sides and bottom reserving that to add to your stuffing mixture.
After you stuff them place them back in the oven for around 20 minutes or until heated through. We enjoyed every bite!!
