The Ultimate Chipotle Pork Nachos

Whisk together the lime juice, garlic, cumin, vegetable oil and chopped chipotles with 1/2 teaspoon salt. Rub the marinade all over the pork tenderloin and refrigerate for 1 hour. Preheat oven to 475 ºF. Roast the tenderloin on a foil-lined baking sheet for 20 minutes, or until a meat thermometer inserted at the thickest part of the tenderloin registers a minimum of 145 ºF for medium-rare. Remove the tenderloin from the oven, transfer it to a cutting board and allow it to rest for 10 minutes before slicing into bite-sized pieces. Reduce oven to 400 ºF. Assemble the nachos by layering chips with cheese, black beans, olives and cubes of tenderloin in an oven-safe 13-by-9-inch baking dish. Bake nachos for 5 to 10 minutes, or until cheese is fully melted. Remove nachos from oven and top with guacamole, salsa and sour cream. Garnish with chopped scallions and serve immediately.
