From LAtimesblogs: The president of the Association of Lebanese Industrialists, Fady Abboud, is preparing a lawsuit in international courts against Israel for "taking the identity of some Lebanese" meals:

"...the Jewish state is trying to claim ownership of traditional Lebanese delicacies such as falafel, tabbouleh and hummus [costing Lebanese] tens of millions of dollars annually. ... The Israelis are marketing our main food dishes as if they were Israeli dishes".

According to Wikipedia, though, it's not at all certain that these dishes originate from Lebanon. Most evidences lead to ancient Egypt and Syria. Read more about the history of Falafel and Hummus on Wikipedia.
