Not in Pakistan but in Punjab primarily, Haleem is eaten with naan or bread. Sorry to say but eating Haleem with nan or bread is pretty insulting towards this dish. Haleem must be enjoyed on its own. Well, this reminds me that I should ask my wife to prepare some. Just few days ago I purchased excellent quality shanks and loin.
As far as Harees(a) goes, it is primarily a middle eastern cuisine that should also be enjoyed on its own like the Arabs do. However, we have adapted it to eat with naan, which is fine, it is just not the authentic way of eating it.
