In a large kettle, brown 1 1/2lb ground beef OR 2 - 3 cups cooked, cubed chicken. Add 10 cups water and bring to a boil. While stirring, slowly add entire amount of soup mix. Reduce heat and simmer, uncovered for approx. 1 hour. Sprinkle soup bowls with crushed tortilla or corn chips before serving, if desired. Not recommended for crock pot, stovetop only
