Using a food processor to make pork tacos can help you achieve a perfectly seasoned and tender filling. Start by seasoning pork shoulder with a mixture of spices such as cumin, chili powder, garlic powder, and oregano. Use the food processor to finely chop onions, garlic, and jalapenos. Sauté the chopped vegetables in a pan until they are soft and fragrant, then transfer them to the food processor and pulse until they are finely chopped. In the same pan, sear the seasoned pork shoulder until it is browned on all sides. Transfer the pork shoulder to a slow cooker and add the chopped vegetables, along with some broth and lime juice. Cook on low for 8-10 hours, or until the pork is tender and easily shreds. Serve the shredded pork in tortillas with your favorite toppings, such as salsa, guacamole, and cilantro.
