Place all pork ingredients into the slow cooker and cook on high for 3-4 hours or until pork is cooked through.
Once pork has been cooking for 3 hours, begin cooking the squash.
Preheat oven to 400°, slice the squash, remove all of the seeds and then continue slicing the squash into pieces.
Place squash in a large bowl and pour melted butter and sage overtop; stir to combine.
Put squash on a baking sheet (you may need 2 baking sheets), making sure none of the squash is touching.
Place in the oven and bake for 25 minutes, flipping the squash after about 12 minutes. You'll know the squash is cooked once it's soft when you bite into it.
Once cooked, put the squash on a plate, pour pork overtop and grate some cheese over the entire dish (this is optional, but gruyere or parmesan is recommended!).
