Preheat oven to 350. Cut the acorn squash in half and scoop out the seeds. Place on a baking sheet coated with cooking spray. Bake about 30-40 minutes or until soft.
Heat a skillet over medium heat. Coat with cooking spray. Add the onions and pepper. Cook about 3-4 minutes until it starts to soften. Add the chicken sausage.
While that cooks, coop out the inside of the acorn squash, leaving the skin intact. Once the chicken sausage is golden brown, add the squash to the skillet.
Add the spices, balsamic vinegar, and the stevia or sugar. Stir and cook about 3-4 minutes or until mixed well and heated through.
Turn on your broiler. Place the acorn squash face up on a baking sheet. Sprinkle some cheese inside the squash (reserving about half). Divide the chicken sausage mixture in half and add to each squash. Sprinkle the remaining cheese over them.
Place under the broiler for about 5 minutes, or until the cheese melts and starts to brown.
