Once only found in Middle Eastern restaurants or ethnic food stores, hummus has become a surging business for food companies here in the U.S. and abroad. The chickpea (garbanzo) bean spread is no longer a secret and limited only to those who were fortunate enough to have a Lebanese restaurant in the neighborhood. Hummus has now gone corporate, with brands such as Tribe and Sabra (a Strauss Group and PepsiCo partnership) enjoying popularity and impressive sales: $325 million at last count in 2010.
