Chopped Salad with Lemon Zest Vinaigrette

Too sour! I like lemon, and especially lemon zest, but for us this salad was too much. I could hear Gordon Ramsey inside my head asking "what are you going to do to balance all that acid? What, you forgot some sugar?"
I did like the mix of vegetables, and perhaps I should have added a bit less dressing to the salad, but...

On the other hand, this recipe made me go out and seek ricotta salata. That cheese really made up for some of the other deficiencies of this dish.
