There's a HUGE market for jarred sauces and I just don't understand it. When the Tuttorosso tomatoes are on sale, you can get them for like 80 cents a can. You buy a dozen cans, put them under the sink, and they keep pretty much forever. Even if you're cooking for one, you just make a can at a time. Even a thirty minute marinara sauce is heads and shoulders better than anything you'll get out of a jar.
