Take a roast and slice it into linear chunks 1 " or so thick. Marinade in citrus, cumin, Cilantro Chipotles, etc for 24 hours. Drain marinade, put on flat top and sear until inter 125, then pull and rest. While resting, put some sliced peppers and onions on the flat top that have been briefly soaked in olive oil and lime juice. Slice roast thin and put in Tortillas or serve with black beans.
