How do I make this?

There has got to be a way I can make this without the box, right?  We all like it, but DH will literally sit and eat the entire box.  And at about 3600 mg of sodium, I would love to change that.  Bonus points if I can do it in the crock pot (this may not even be a possibility, but I just want to throw that out there).
