I always use 250 ml of water to mix the soup in one pan and heat on low to medium heat. In another pan I saute my 2 cups veggies, add whatever spices I want and then add anywhere from 1 to 1-1/2 cups of low sodium fat free chicken broth. After bringing veggie/broth mixture to a boil, I add the veggie/broth to the soup and it makes a large serving bowl of soup that fills me up very well. I never eat any of the soups "straight".
