A tiny ball-shaped pasta, Israeli couscous is also known as pearl couscous and in Israel, goes by the name of “ptitim.” When cooking it as a dish by itself, we like to toast the couscous in a pan to impart a nutty flavor, but here we treat it more like a pasta. Adding turmeric to the cooking water imparts a fun and vibrant golden color that works great with all of the green components in the salad. In the summer, when zucchini is in its prime, it's nice to enjoy it uncooked, as we do here, although you could roast the zucchini instead.
