I threw this together for dinner tonight and it was pretty tasty, so I thought I'd share.
1 butternut squash, cut in half lengthwise
1/2 onion, diced
4-5 mushrooms, diced
1/2 apple, cubed
lots of butter
oil of choice (i used bacon fat)
Fill a glass baking dish with about 1 inch of water and place squash halves in the dish cut side up. Slather a healthy coating of butter onto the surface of the squash, then sprinkle with cinnamon, salt, and pepper. Bake of 350 F for 40-50 mins or until tender.
While the squash is cooking, saute the onions and mushrooms in oil for a few minutes, then set aside. Then brown the apple cubes in oil and set aside.
For the last 5 minutes of cooking time, sprinkled the squash with some balsamic vinegar. After it has cooled some, scoop the squash into a mixing bowl and mix in another tablespoon or so of butter, the onion and mushroom mixture, and the apples. Enjoy!
I also cut up a few leftover sweet sausage links and added them to the mix as well.
