White Plains resident and home cook Bindu Grandhi has authored Spice Up Your Life: The Flexitarian Way ($17.99, Cedar Fort), a 114-recipe cookbook endorsed by celebrity chef Emeril Lagasse. The flexitarian diet consists of eating foods low in saturated fats and high in fiber and products that are minimally processed; essentially, lean protein (chicken and fish), whole grains, spices, fresh fruits and vegetables, legumes, and nuts. Grandhi will do a cooking demo and book signing at Barnes & Noble (2614 Central Ave, Yonkers 914-771-6400) Saturday, November 14 at 7:30 pm.
