Pulled Pork Tacos

4 pounds pork roast, netting removed
1 large yellow or white onion, chopped
2 Tablespoon Worcestershire sauce
1 lime, juice
3 cloves garlic, minced
1/3 cup cilantro, chopped
1 4-ounce can of green chiles, chopped
4 1/2 teaspoons salt
4 teaspoons cumin
2 1/4 teaspoon freshly ground black pepper
3/4 teaspoon sweet paprika
1/2 teaspoon garlic powder
1/4 teaspoon onion powder
1/4 teaspoon cayenne
1/4 teaspoon dried oregano
1/4 teaspoon dried thyme
8 Tortillas
Cheddar Cheese, shredded
4 whole Limes sliced in wedges

Add onion, Worcestershire sauce, lime juice, garlic, cilantro and green chiles to the slow cooker. Mix all of the seasonings in a bowl and rub half of the seasonings onto the roast. Add the rest of the seasonings to the onion mixture in the slow cooker. Center the roast, fat side up on top of the onion mixture. Cover and slow cook on high for 4 to 6 hours or until tender and easily falls apart with a fork. Before serving, remove as much fat as possible from the pork then shred with two forks.
Make or warm the tortillas. Top tortillas with pork and cheese. Serve with lime wedge to be squeezed over the taco.
