No barbecue sauce here! Smoky chipotle chiles in adobo set this pulled pork apart. Martha made this recipe on Cooking School episode 402. It comes from our book, "One Pot: 120+ Easy Meals from Your Skillet, Slow Cooker, Stockpot, and More."
In a 5- to 6-quart slow cooker, combine onion, oregano, bay leaves, chipotle, adobo sauce, tomatoes (and puree), salt, and pepper. Add pork and turn to coat completely.
Cover and cook on high until meat is pull-apart tender, about 6 hours. Transfer pork to a bowl; shred with two forks. Return pork to pot, and toss with sauce. Discard bay leaves.
Serve pulled pork with rolls, coleslaw, and pickles.
