Cheesy Spaghetti Squash Casserole (Vegetarian)

Proof that you don't need to add meat to spaghetti squash to make a great dish! This is easy to make and very flavorful; feel free to adjust seasonings to your taste. The crushed red pepper is optional, but if you have it on hand I think it adds to the flavor. Try to use REAL parmesan, not the stuff that comes in the green can! I'm unsure of the origin of this recipe, but it's a keeper!
