Bake spaghetti squash at 375 for 1 hour. While this is cooking, wash and chop the basil and put into a food processor or vitamix. Add pine nuts, olice oil, and 1/4th tsp salt. Blend until smooth.
Once spaghetti squash is done, use two forks and gently scrape out the inside of the squash into a large bowl. Then add the basil mixture to the squash and stir. Top with the halved tomatoes and add salt if needed.
Serve with meatballs or any other protein based side for a full meal.
