Over the past 15 years Mr Karounis has helped grow Our Big Kitchen or OBK, a non-denominational food service staffed mainly by volunteers.
For almost 20 years, OBK has helped sustain a city’s most vulnerable.
They’ve already set up a sister OBK in America’s Los Angeles and provided inspiration to other international projects.
