01 - Place the chicken breasts in an even layer across the bottom of the slow cooker.
02 - Sprinkle the ranch seasoning and taco seasoning evenly over the top of the chicken, coating each piece thoroughly.
03 - Pour the chicken broth around the edges of the chicken rather than directly on top 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 shreds apart easily.
05 - Using two forks, shred the chicken directly in the slow cooker and stir to coat the shredded meat evenly in the accumulated juices and seasonings.
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, diced tomatoes, cheddar cheese, sour cream, cilantro, and a generous squeeze of fresh lime juice. Serve immediately.
