I like to make SE style pulled pork bbq burrito.  It is nothing really awesome, and is probably  being done a bunch, but I like to fill a large tortilla with smoked pork--really shredded, and then pour on a good amount of a vinegar based bbq sauce, a pile of home-made slaw, and a few steak fries.  Sometimes I will add cheese inside with some diced jalapenos.  This isn't something your probably looking for, but I just had to share something I think is really good.  A friend of mine made something he called Korean BBQ chicken, which had some sort of hot and sort of sweet sauce then he grilled the chicken breasts and cut them up.  He placed them in a corn tortilla with tomatoes, a little lettuce, and olives.
