Easy Spaghetti Squash with Marinara

Preheat the oven to 450 degrees.  Line a cooking sheet with foil.  Split squash in half and remove seeds.  Season with olive oil, salt and pepper.  Place flesh side down and roast for 30-40 minutes.  Let rest until cool enough to handle.  Scrape the squash out of the skin with a large spoon, and toss with marinara.  Serve immediately.
