01 - Place the chicken breasts in an even layer at 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 on top to keep the seasonings in place.
04 - Cover the slow cooker and cook on low for 4 to 6 hours, or until the chicken is fork-tender and easily shreds apart.
05 - Using two forks, shred the chicken directly inside the slow cooker and stir thoroughly so the meat absorbs the seasoned juices.
06 - Warm the tortillas according to package directions until pliable and lightly toasted.
07 - Fill each warm tortilla with the shredded ranch chicken and top with lettuce, tomatoes, cheddar cheese, sour cream, cilantro, and a squeeze of fresh lime. Serve immediately.
