If you like, serve it with some sour cream dolloped on top.  1 1/2 cups reduced-sodium chicken broth  1/4 cup sherry vinegar  2 stalks celery, thinly sliced  1 large onion, chopped  1 large red bell pepper, seeded and chopped  3 cloves garlic, minced  1 tablespoon ground cumin  1 teaspoon salt  1/2 teaspoon freshly ground pepper  3 pounds flank steak, trimmed of fat, each steak cut into thirds  1/2 cup packed fresh cilantro leaves, chopped  1/2 cup chopped pickled jalapenos  10 corn tortillas, heated (see Tip)  Combine broth, vinegar, celery, onion, bell pepper, garlic, cumin, salt and pepper in a 6-quart slow cooker. Add beef, submerging it by tucking the vegetables under, over and between the pieces.  Put the lid on and cook on low until the meat is fork-tender, about 8 hours.   Transfer the meat to a cutting board; let stand for 10 minutes. Shred the meat with 2 forks and return it to the slow cooker. Stir in cilantro. Garnish with jalapeno and serve warm tortillas on the side.   Wrap corn tortillas in foil and bake at 300°F until steaming, about 10 minutes.    |    |   |              Recipe Summary Prep Time: 25 minutes  Cook Time: 8 hours 5 minutes  Yield: 10 servings      | User Rating: |    |    |    |    |     |     |     |     |    |
