Tomato sauce (or gravy as my Italian-American family called it) is one of the few sauces I can still eat since my angioplasty and being put on a no-salt, no-sugar, no-fat diet.
But making sauce from canned tomatoes can create a product with way too much salt, depending on the tomato brand and variety you buy. 
But who has hours to spend making tomato sauce more than on a rare occasion? So I’ve also been searching for prepared tomato sauce with little or no salt. Standard brands in mainstream supermarkets have tons of salt in them. But I found this Muir Glen product that fits my needs in a pinch.
You can see on its nutrition label that it has only 10 mgs per serving or 70 mgs for the entire can. The can is enough for a meal for two, or two servings, in my estimation, not the seven servings the can indicates. But even then, half a can and 35 mgs or salt is several hundred mgs less than any mainstream brand. The sauce itself was a bit watery for my taste, but it worked well to use it for baking chicken in tomato sauce and giving some flavor to otherwise dry chicken breasts.
