I'm completely stumped. We're doing mezze to start, so there will be loads of houmous and tabbouleh, salads, cheese, olives, that kind of thing. I'm doing chicken with lebanese potato salad and moroccan carrots (watch me mix-and-match recklessly!) for carnivores, and a salmon with a persian sauce for people who eat fish. But I am completely stumped for a main course for the veggies. Any ideas?
