Preheat oven to 350 degrees. Arrange chicken tenderloins or sliced chicken breast on a pan in a single layer.
Cook chicken for 20-30 minutes or until done.
While chicken is cooking, prepare other ingredients and combine in a large bowl. (except the tortillas, of course!)
Cut cooked chicken into small pieces and add to the bowl. Refrigerate for at least 1 hour.
Roll filling into tortillas and enjoy!
