01 - Place the chicken breasts (or thighs) 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.
03 - Pour the chicken broth around the edges of the chicken rather than directly on top, which prevents washing off the seasonings.
04 - Cover the slow cooker and cook on low for 4 to 6 hours, until the chicken is very tender and shreds easily when pressed with a fork.
05 - Using two forks, shred the chicken directly inside the slow cooker. Stir well so the shredded meat absorbs the juices and seasoning throughout.
06 - Warm the tortillas according to the package instructions until pliable and lightly toasted.
07 - Fill each warm tortilla with the shredded ranch chicken. Top with shredded lettuce, diced tomatoes, cheddar cheese, sour cream, cilantro, and a generous squeeze of fresh lime. Serve immediately.
