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.
Just to stick my nose in, most people forget that Mexico has an extensive coast line and a lot of their quisine includes seafood. You can find fish tacos in some places, but how about something with shrimp? People go nuts for shrimp, and until the gulf oil spill and some problems with the Asian suppliers, it was fairly affordable. You can marinate and grill it or poach it with some spices and peppers, chill it and serve it as a cold dish. Spicy chilled shrimp with some crunchy veggies sounds good to me, and I don't even like spicy food.
MASH beans in bowl with back of spoon or potato masher. Add cream cheese; mix until well blended. Stir in peppers and steak sauce. Spread bean mixture evenly onto tortillas. Top with meat; roll up tightly.
PREHEAT grill to medium heat. Grill tacos 12 to 15 min. or until crisp and lightly browned; turning occasionally.
