Sometimes feeding just one child can seem challenging. Not for entrepreneur Wawira Njiru, who’s gone from serving lunch to 25 children from a makeshift kitchen to establishing her nonprofit, Food4Education, as a cornerstone of Kenya’s school meals system. Currently serving half a million meals to children every day, she’s now thinking even bigger. Hear about her incredible plan to serve delicious, nutritious daily meals to millions of kids across Africa by 2030. (This ambitious idea is part of The Audacious Project, TED’s initiative to inspire and fund global change.)
