While squash bakes, prepare stuffing. In a medium-sized skillet, add oil, sausage and onion. Fry over medium heat for about 5 minutes to brown sausage. Add apple and sauté an additional 2 minutes. Reduce heat to medium-low and add broth, turmeric and pepper. Cover and simmer about 20 minutes until sausage is thoroughly cooked. Remove from heat and add enough bread cubes to make a moist but not soggy stuffing.
