Preheat oven to 350 degree oven. Cut spaghetti squash in half lengthwise. Scrape out seeds. Lightly brush with olive oil and sprinkle with salt and pepper.
Roast in preheated oven for 45-60 minutes, until squash shreds easily when scraped with a fork. Enjoy with desired toppings: butter & Parmesan cheese, pasta sauce and sausage!
