Step 1
Place the squash, cut side down, in the bottom of the slow cooker. Arrange the meatballs around the squash. Pour the sauce over the meatballs trying not to cover the squash. Place the lid on the slow cooker and cook on high for 4 hours, or low for 6-7 hours. When the squash is done (it will be soft and can easily be pierced with a fork) transfer it to a bowl and allow to cool for a few minutes. When the squash is cool enough to handle, shred the insides with a fork and place in a bowl. Discard the skin.
