Lemon zest adds brightness and citrusy flavor to this chickpea salad. Start by washing your lemon. Use a fine-grater, microplane, or zester specifically designed for citrus fruits. Gently rub the lemon against the grater or zester's surface, gently rotating as you do this. Avoid grating too deeply into the white pith, as that can be bitter. Add this to your lemon dressing and stir.
