Using a sharp knife cut off the very top and bottom of each squash to create a flat base on each side (being careful not to cut through the center cavity).
2. Step
Slice the squash in half, scrape out seeds to create individual bowls for the stuffing.
3. Step
Drizzle each squash half with olive oil, salt, and pepper.
4. Step
Roast in a preheated oven at 400˚F (200˚C) for 40-50 minutes - or until fork tender.
5. Step
While squash is roasting - in a large fry pan over medium heat - heat oil and add Onion, Celery, Salt, Pepper, and Rosemary. Cook until onions begin to soften.
6. Step
Add Garlic and Sausage, until sausage is browned on all sides.
7. Step
Add Apple until slightly softened. Finally mix in Bread Crumbs and Parmesan cheese just until incorporated. Remove from heat.
8. Step
Once Squash has finished roasting (when you can easily poke it with a fork) remove from oven and fill each with prepared stuffing mixture.
9. Step
Return to Oven for 20 minutes - adding a sprinkle of Parmesan cheese to the top for the final 5 minutes.
