To use: 1 can of soup = ⅓ cup of dry mix + 1 ¼ cup of cold water. Heat on medium-high heat (stove top or microwave) until thick, stirring frequently. Use this mixture the same way that you would use a can of cream of mushroom/chicken soup.
Want a more natural alternative to instant bouillon cubes? Skip the chemicals by using Better Than Bouillon (any flavor). Adapt this recipe by not adding the dry bouillon to the dry mix. Instead, add in 1 tsp of Better Than Bouillon to the 1 ¼ cup cold water right before making the soup.
