almost all canned soup are full of salt, preservatives and many other craps
and it is easy to cook your own soup
just water and dry lentils .... cook it for XXX minutes (see the label)
Go to the organic section. You can usually find a lot of canned soups that have a variety of serving sizes. I cook a lot of organic canned chili, with 28 grams of protein per can (14g soy), and 320 calories per can.
