CHICKEN – The real time-saver here is the cooked chicken, which makes this a great dish to use up any leftover chicken (or turkey!) you may have.

ADD-INS – Feel free to add in some cooked brown rice or pasta for more texture to satisfy those heartier appetites! Or add in a bag of vegetable medley with the broccoli and eliminate the chicken for a vegetarian entrée!
