On a Saturday this summer, staff from The Food Trust and cookbook author Leanne Brown led a tour of the market in Philadelphia's Clark Park.

Brown's cookbook "Good and Cheap" is for people who live on a food stamp budget and The Food Trust is on a mission to get nutritious food to more city people.
