Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven.
Substitutions: You can use rotisserie chicken for a quicker prep. If you don't have chicken stock, water or broth substitutes work fine. Fresh cilantro can be replaced with dried if necessary, though fresh is preferred.
Variations: Add black beans or corn for extra texture and nutrients. For a spicier kick, add diced jalapeños or a dash of hot sauce.
