I'm sure someone has tried this, but I can't find on the web too much about it. I'm a big fan of smoked chuck roast. So instead of shredding it and sticking it between two buns, why not put it in a soft flour tortilla, with some grilled onions, fresh cilantro, lettuce, tomato... I mean, it's GOT to be good. I can't see how it can't be.
