Didn't use harissa, air fried the eggplant, added sesame seeds and substituted the arugula with spinach. Made the hummus in advance so the flavour would develop.
We modified the recipe and cooked the chicken by itself first for better flavor. We also used chicken thighs instead. We used baby carrots and celery and a bag of frozen peas. We used store bought pie crusts. It was quite tasty. We were able to make two pies. Froze one for later.
