I would actually recommend making it the night before, and eating it as leftovers, because it was actually better the next day.
I added up the points (using recipe builder on etools), and it turned out to be 7 PointsPlus, if you divided the 9 x 13 pan in to 6 servings. It could probably be less if you used less meat, or crushed tomatoes instead of the sauce. Or if you were able to find (and willing to use) fat free cheese.
Here is what I did. Enjoy!!
(and did I mention that the kids ate it too?)
Have you ever cooked with spaghetti squash? What did you think?
