Mexican Shredded Chicken in the crockpot All you need is chicken breasts, 3 or 4, a jar of salsa, and a pkt of taco seasoning. Dump the salsa and taco seasoning into the crockpot and mix, coat the chicken in it and set the crockpot on high for 4 hrs (or low for longer). Once it’s cooked, shred it with a fork. This chicken is so tender it pulls apart easily. This is good plain, in tacos, and in quesadillas. It’s also make a great protein addition to a salad!
