Many chefs once opposed the idea of changing dishes to accommodate vegetarians, patrons suffering from food allergies and anyone else with dietary restrictions. That's changing along with high-end restaurant menus as more Americans adopt Meatless Mondays and groups raise awareness about celiac disease and gluten intolerance. "I've realized it's not that hard to give the same dining experience to someone who doesn't eat gluten as long as you keep an open mind as to what you can and can't do," chef Noah Sandoval says.
