Our arugula salad, made with an easy lemon vinaigrette, pearl couscous, cucumbers, and feta, is crave-worthy. Once you make it, you’ll be itching to make it again. We particularly love pearl (often labeled Israeli couscous) for this arugula salad. It cooks quickly and gives the salad enough substance to stand on the plate by itself. You could swap the couscous for pasta, quinoa, or other cooked grains like barley or wheat berries.
