01 - Arrange 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, coating each piece thoroughly.
03 - Pour the chicken broth around the edges of the chicken rather than directly on top, which prevents the seasonings from washing off.
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 in the slow cooker. Stir the shredded meat so it absorbs the seasoned juices and is evenly coated.
06 - Warm the tortillas according to 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, chopped cilantro, and a generous squeeze of fresh lime juice. Serve immediately.
