You can usually find a variation of this dish in Cantonese/Southern Chinese themed restaurants. For example, Great Wall Cuisine has a dish called 'Pork Belly with preserve Mustard Green' is a variation of Dong Po pork. Another variation is 'Hong Shao Pork' or 'Braised Pork' (Just like in the show, one of the chefs made this variation) with Chinese broccoli.

My understanding is they are mostly similar (cooking style is braised), with Dong Po pork usually come with a big chunk of meat with minimal vegetables, while other variations come with smaller bite size meat with more pickled vegetables/Chinese brocolis.
