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, or until the chicken is fork-tender and easily shreds apart.
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 instructions until pliable.
07 - Fill each warmed tortilla with the shredded ranch chicken, then top with lettuce, diced tomatoes, cheddar cheese, sour cream, cilantro, and a squeeze of fresh lime. Serve immediately.
