There is usually a whole section in the supermarket dedicated to canned tomatoes. There are dozens of different brands and varieties. After having tried most of them, Jovial is by far my favorite. Grown on small organic, family farms in Italy, they are fresh, 100% organic and without any added salt or preservatives. Most importantly, they are canned in glass jars, not aluminum, which tastes much better and doesn’t leech harmful metals. Jovial tomatoes come in three different varieties: diced, whole and crushed tomatoes. They are available at most Whole Foods markets, amazon and many natural food stores.
