Ingredients
1 canned chipotle chile, in adobo sauce
3 garlic cloves
1/2 cup coarsely chopped white onion
2 tablespoons fresh lime juice
1 teaspoon sherry vinegar
1 teaspoon dried Mexican oregano
1 pound pork tenderloin, trimmed of fat
1 can (19 ounces) black beans, drained and rinsed
1 cup grape tomatoes, quartered
1/4 cup finely chopped white onion
1/4 cup finely chopped fresh cilantro
3 tablespoons fresh lime juice
2 teaspoons minced canned chipotle chile, in adobo sauce
1/2 teaspoon ground cumin
Preparation
Make the pork marinade: Process chile, garlic, onion, lime juice, vinegar, and oregano in a blender until smooth. Rub marinade all over the pork. Transfer pork to a dish, and cover with plastic wrap. Refrigerate overnight.
Preheat oven to 350 degrees. Heat a grill pan over high heat. Grill pork until seared on all sides, about 2 minutes per side. Transfer pan to the oven; cook until an instant-read thermometer inserted into center of meat registers 145 degrees, 20 to 25 minutes. Let pork stand at room temperature 5 to 10 minutes before slicing.
Meanwhile, make the salsa: Stir together the black beans, tomatoes, onion, cilantro, lime juice, chile, and cumin in a small bowl. Serve with the pork.
