- Prepare the dry rub.  In a small bowl, mix the dry rub ingredients: salt, pepper, cumin, coriander, garlic powder, and cayenne pepper.  Rub the mixture evenly over all sides of the pork. 
- Sear the pork.  Heat the olive oil in a medium skillet over medium-high heat.  Carefully sear the pork for 1-2 minutes on each side, turning with tongs, until browned.  Then, transfer the pork to your slow cooker. 
- Cook.  Pour the water and liquid smoke into the slow cooker.  Cover and cook the pork on high for 4-4½ hours or low for 8 hours until tender. 
- Shred.  Once cooked, carefully remove the pork from the slow cooker and place it on a cutting board.  Then, shred the pork into bite-sized pieces using two forks, discarding large fatty pieces. 
- Season.  In a large bowl, combine the shredded pork with salt, pepper, chili powder, smoked paprika, and cayenne pepper.  Mix thoroughly using tongs to make sure the pork is evenly seasoned. 
- Make sauce.  Whisk together the brown sugar and ¾ cup of green chile enchilada sauce in a small saucepan.  Heat over medium-low, stirring until the sugar is fully dissolved.  Then, pour the sauce over the shredded pork and toss gently with tongs to coat evenly. 
- Serve. Use the shredded pork as a filling for burritos, tacos, quesadillas, enchiladas, or even salads and rice bowls.  For burrito or taco ideas, see notes below.
