In the crockpot, place 4-6 boneless, skinless chicken breasts, 1 package of dry taco seasoning, 1 package of dry chicken gravy mix (sounds weird...but trust me, this is gonna be good!), and 1 small can chicken broth. Slow cook on low for six hours. About four hours into the cooking time, shred the chicken with forks or cut up into small pieces with a kitchen scissors. Then continue cooking until the six hour mark so that the chicken can absorb some of the yummy liquid! Drain with a slotted spoon and place on warmed tortillas. Then top with your favorite taco toppings (ie. lettuce, tomato, black olives, shredded cheese, sour cream, guacamole, and salsa). Soooooooooo good!
