The lemon zest is an odd choice for a supposedly savory dish. The citrus overwhelms the other more subtle flavors and leaves you with the feeling that you've just eaten a dessert rather than a side dish. If I were to make this again I would leave out the zest entirely.
YUMMY!!!!! I made this for the holiday weekend and love it. I would add more arugala and celery the next time I make it and I will be making it again!!!
