01 - Arrange the chicken breasts or thighs in an even layer across the bottom of the slow cooker.
02 - Sprinkle the ranch seasoning mix and taco seasoning mix evenly over the top of the chicken.
03 - Pour the chicken broth around the sides of the chicken rather than directly over it to prevent washing off the seasonings.
04 - Cover the slow cooker and cook on low for 4 to 6 hours, until the chicken is fork-tender and easily shreds apart.
05 - Using two forks, shred the chicken directly in the slow cooker and stir thoroughly so the meat absorbs the seasoned juices.
06 - Warm the tortillas according to the package instructions until pliable and lightly toasted.
07 - Fill each tortilla with the shredded ranch chicken and top with lettuce, tomatoes, cheddar cheese, sour cream, cilantro, and a generous squeeze of fresh lime. Serve immediately.
