Cut squash in half. Scoop out seeds. Place cut-side down in a baking dish with enough water to come about 1/2 inch up the sides. Bake at 350deg for 30-40min. Take out and let cool.
While squash is baking, cook rice according to directions.
When rice is cooked and squash is cool enough to handle, scoop out the flesh of the squash into a bowl, leaving about 1 inch in the rind. Mix the cooked squash with the cooked rice and the sausage. Fill in the shells of the squash, drizzle with maple syrup to taste (1-2tbls over each maybe?) and bake in 350 oven for another 45min to an hour. Internal temp should be 165 by meat thermometer.
-- You can saute mushrooms and mix this in with the filling.
-- Add chopped apples (fine chop, about 1/4inch dice)
-- Add chopped onions to the mix, or saute them first and mix them in
-- Switch out the grains, use barley, buckwheat, amaranth or quinoa
