Preheat the oven to 375 degrees.
Remove the top from the pumpkin.
Scoop out the seeds and all the stringy pieces.
In a mixing bowl combine 1 cup of oats, 2 cups of water, brown sugar, and the spices and salt.
Pour inside the pumpkin. If you still have space add more oats, keeping the ratio 1 parts oats to 2 parts water. Add more sugar and spices if you wish.
Place the pumpkin in a baking dish large enough to catch anything that runs over.
Bake for 40-50 mintues, until the pumpkin feels soft on the outside and the oatmeal is cooked and slightly browned on top.
Serve right from the pumpkin with some maple syrup if you like.
