Slow Cooker leftover soup

Today's way of saving was to throw together a leftover soup.  Into my crock pot (I use one of several different sizes at least twice a week) went a huge bowl of mashed potatoes, diced spiral cut ham, chives, an onion chopped, chopped celery and two boxes of low sodium organic chicken stock (I bought a ton on sale at Shop Rite earlier in the month for just $1.50 a 32 oz container) and some baby carrots.  Lots of freshly ground black pepper.  On low for 5 hours and stir.  Not my best work, but tasty.  My father enjoyed it. DH doesn't eat soup unless it's very thick like a chili or chowder.
