Spaghetti Squash Casserole Print 8 LikeDislike By Gretchen Otte It looks like spaghetti, kind of tastes like spaghetti, butttt it’s yummier and about one third of the carbohydrates. It’s a Spaghetti Squash Casserole. Major ingredients include: fresh mozzarella, organic tomato, and squash! NO PASTA! Brilliant! This kind of meal doesn’t spike my blood sugars like regular pasta would, so this is a great substitute!
