Slow Cooker Macaroni and Cheese

Slow Cooker Macaroni and Cheese
 
This was a very easy recipe and it turned out pretty tasty.  The only suggestion I have is to eat it right away because, as it sits, it gets a "cottage cheese" texture.  It tastes the same, but it feels a little weird in your mouth.  :)
