Winter is a good time to get out the crock pot and slow-cook a meal. Pulled pork for sandwiches is especially suited to this kind of cooking. The key is to use a cut of meat, boneless pork butt roast, that has a lot of flavor to begin with. The moist heat and long cooking time tenderizes the pork, intensifies the flavor and the end result is that the pork just literally pulls apart. For this recipe, I added some Cajun-inspired spices to heat things up.
