Tomato based pasta sauce is easy to make, inexpensive, and can be suited to your tastes. Besides the Italian herbs and spices, I only add onions and fresh garlic to the sauce. This makes it versatile. I add meatballs or sausage when I reheat it later to the dish I’m making. Hubby isn’t a big veggie fan so I stick to onions and garlic. I make big batches of this and freeze them in 4 cup containers. One container is perfect for spaghetti dishes, two for baked rigatoni or stuffed shells. If you forget to defrost the sauce, you can still warm it up fairly quickly in a pan on medium low. I buy my tomato sauce in bulk at Costco as well as the tomato paste.
