Who says a college student can’t change the world? When Eli Winkelman was an undergrad at Scripps College in California, she started a program called Challah for Hunger. The idea started out small: bake fresh, delicious challah every week and sell it to students and faculty to raise money for hunger and disaster relief.

The program was a hit (even former President Clinton took notice) and began to spread to other colleges. As of 2009, Challah for Hunger had chapters on 30 campuses across the country and had raised more than $130,000, with half of the proceeds going to American Jewish World Service’s Sudan Relief and Advocacy Fund, and half going to local, national, or international organizations chosen by campus organizers.

Now graduated, Winkelman continues to head Challah for Hunger as its national coordinator, consulting with volunteer leaders in college communities to start Challah chapters of their own. She stands as a powerful example of how a DIY-spirit coupled with a passion for Jewish and social justice values can make a big impact.
