Ingredients

1 medium onion, diced

1 teaspoon dried oregano

2 dried bay leaves

1 chipotle, in adobo sauce, minced

1 tablespoon adobo sauce

1 can (28 ounces) crushed tomatoes

1 can (14.5 ounces) whole tomatoes in puree

2 teaspoons coarse salt

1/2 teaspoon ground pepper

2 3/4 pounds boneless pork shoulder, trimmed and halved crosswise

Flour tortillas, lightly toasted, for garnish (optional)

Grated cheddar cheese, for garnish (optional)

Sour cream, for garnish (optional)

Preparation

In a 5-quart slow cooker, combine onion, oregano, bay leaves, chipotle, adobo sauce, tomatoes (and puree), salt, and pepper. Add pork; toss to coat with sauce.

Cover; cook on high setting until meat is pull-apart tender, about 6 hours (do not uncover while cooking).

Transfer meat to a large bowl; shred with forks, discarding any gristle. Return meat to pot; toss with sauce.

To serve, discard bay leaves; if desired, garnish with tortillas and cheddar or sour cream.
