Cut the cauliflower into quarters removing the stem and leaves. Chop Cabbage into large chunks. Add both to a pot of salted water and cook until cauliflower is fork tender.
Drain water and separate the cauliflower and cabbage. Rough chop the cabbage and return the cauliflower to the original pot. Add butter, salt and cream cheese and mash with a potato masher until smooth.
Next add the chopped cabbage and chives along with the cheese and fold until cheese has melted.
