I am a vegetarian and it is abhorrent to me to have an animal leg on my table at Pesach. I have been told that somewhere in the Talmud it says that a roasted beet can take the place of a roasted shank bone. Can you help me find the source?

Dear Bonnie Horwitz,

The source is the Babylonian Talmud, Tractate Pesachim 114b. There Rabbi Huna is qouted as saying "beets and rice" can be used for the two cooked foods on the Seder plate.
