Mario Lopez shares a family recipe to celebrate his new children's book, "Mud Tacos," written with his sister, Marissa Lopez Wong, and illustrated by Maryn Roos.
Trim fat off meat, then add liquid and rest of the ingredients into a slow cooker. Cover and cook on low for 8 to 10 hours. Remove meat from the liquid and shred with your fork when cooled. To build the tacos: Place shredded pork in a tortilla and top with crema, cilantro and cotija cheese. Squeeze fresh lime juice on each taco and enjoy!
