kiran sridhar founded waste no food, a website and an app that lets businesses donate leftover food to charities. the hunger at home has already used the app to help silicon valley companies and restaurants donate 10,000 meals that otherwise would go to the landfill. >> instead of putting a cheese tray out for 500, we deconstruct and put the different components in smaller platters, and when not used and it can't be consumed by team members or by future guests, then it's donated safely. >> now, san jose is the first city to partner with waste no food. hunger is a big problem, sadly, in the wealthy silicon valley. one in four residents lives with hunger. one of those residents is in the studio with me right now, kelly kang. she is a wife, a mother of four, and their family struggles regularly to make ends meet. kelly, thank you for being here today. >> thank you for having me. >> i really appreciate the fact you're willing to come forward and talk about what's going -- four kids. how old are your kids? >> they're 11, 9, 5, and 2 1/2. >> had to think about that for a minute, right? >> ye
