I've just sliced my gammon joint on my slicer so that I get nice slices rather than chunks, I cooked mine last night popped it in the slow cooker for 6 hrs, I didnt add liquid I never do.
Any leftover I make a chicken and ham soup (used to make a pie but lets not go there) throw leftover ham & chicken into 1.5 pints water add chicken cube, pinch dried herbs as much veg as you like, simmer for 30-45 mins yummy
