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 chicken, coating all surfaces.
03 - Pour the chicken broth along the sides of the slow cooker, avoiding pouring directly over the seasoned chicken to prevent washing off the spices.
04 - Cover 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 inside the slow cooker. Stir thoroughly so the shredded meat absorbs the accumulated juices and seasonings.
06 - Warm the tortillas according to package directions until pliable and lightly toasted.
07 - Fill each warmed tortilla with the shredded ranch chicken. Top with shredded lettuce, diced tomatoes, cheddar cheese, sour cream, chopped cilantro, and a generous squeeze of fresh lime. Serve immediately.
