01 - Place the chicken breasts in a single layer at 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 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, until the chicken is very tender and shreds easily with a fork.
05 - Use two forks to shred the chicken directly in the slow cooker, then stir to coat the shredded meat evenly in the juices and seasonings.
06 - Warm the tortillas according to package instructions until pliable.
07 - Fill each tortilla with the shredded ranch chicken and top with lettuce, tomatoes, cheddar cheese, sour cream, cilantro, and a squeeze of fresh lime. Serve immediately.
