Grandma's Tomato Sauce

Tonight was my son, Nolan's 9th birthday and he requested Spaghetti & Meatballs.  It's his favorite!  He has become even a bigger fan since I've started making this recipe for tomato sauce.  It makes a ton and we've been making it just about every week lately because it's so good and can be used in so many dishes!
