This is a great crushed tomato product for starting either pasta sauce or pizza sauce.  I suggest a few other additions for a quick sauce (granulated garlic, crushed fennel, dried oregano, salt, black pepper, and if you have it some dehydrated onions.  That makes are really quick pasta sauce (done in about ten minutes) which is much less expensive than buying jarred pasta sauces and with easy to identify ingredients.  For pizza sauce, I add more of the same ingredients to give a stronger flavor and cook it until it thickens.  You can use it warm on your pizza or cool and store it in the refrigerator for a day or two.
