NutriChef was created on the principle that healthy home cooking should be attainable to all, regardless of skill level and economic status. Starting in 2014, we noticed the disconnect in our lives and in the lives of those around us. We were so busy, always rushing forward, and our health and personal lives suffered. We needed to find some way to slow down and put our health first, all without sacrificing convenience or taste. Could we somehow create healthier versions of our favorite foods, easily in our own kitchens? The answer was a resounding yes, and NutriChef was born.
