Notes.....
 * I don't use celery in mine because no one in my family likes cooked celery.
 * I usually will use 2lbs hamburger and 16oz of Velveeta which makes a much thicker soup and fills you up better.
 * Sometimes I will use the Mexican Velveeta to spice it up a little, that's a really good variation :)
