On Thursdays and Fridays at the quad at the University of Illinois at Urbana-Champaign, a table has quietly blinked into existence. A hand-made felt banner serves as a name-tag: Challah for Hunger. Every two hours on the hour, a new pair of Jewish students approaches the table to relieve those who had been on duty. Passer-bys stop frequently on their way to class, often just to ask “What’s challah?” while the bold and hungry will snag a free sample. Every so often, a sale is made, and the transaction is warm and friendly. In what can sometimes be a large, impersonal campus, the Challah for Hunger table has formed an oasis of philanthropic spirit and camaraderie among its volunteers.
