Instructions

Step 1: In a small bowl, combine 2 tbsp chili powder, 1 tbsp ground cumin, 1 tbsp smoked paprika, 1 tsp garlic powder, 1 tsp onion powder, 2 tsp salt, and 1 tsp black pepper. Rub this spice mix evenly over 3 lbs cut pork shoulder chunks.
Step 2: Place the seasoned pork into the slow cooker and pour 1 cup chicken broth around it. Cover and cook on low for 8 hours or on high for 4-5 hours until pork is tender and pulls apart easily.
Step 3: While pork cooks, prepare pickled onions by combining 1 cup apple cider vinegar, 2 tbsp sugar, and 1 cup water in a saucepan. Bring to a boil, stirring until sugar dissolves. Remove from heat and pour over 1 large thinly sliced red onion in a heatproof bowl. Let cool and refrigerate until ready to serve.
Step 4: When pork is done, shred it using two forks and mix with cooking juices in the slow cooker.
Step 5: Warm 12 small corn tortillas in a dry skillet over medium heat for 20 seconds per side until pliable.
Step 6: Assemble tacos by filling tortillas with pulled pork, a spoonful of pickled onions, and garnish with 1/4 cup chopped fresh cilantro and lime wedges on the side.
