Most Passover Seder nights are far from vegan- friendly. From the egg and shankbone on the Seder plate, to the chopped liver, chicken soup and pot roast during the meal – it’s not a night made for vegetarians.But PETA , the People for the Ethical Treatment of Animals, has launched an appeal to convince people to veganize their Passover Seder, and they’ve recruited comedian Carol Leifer to further the cause.In a video campaign posted to social media last week, the Jewish comedian – known for her stand-up as well as writing for Seinfeld, Saturday Night Live and The Larry Sanders Show, offers tips and ideas for veganizing.Leifer opens the video by explaining how she became vegan, “because, as a Jewish lesbian, I wasn’t part of a small enough minority.” She also offers a “quick impression of my Passover Seder: ‘What page are we on?’” The comedian notes that, when it comes to the Seder plate, maror, haroset and karpas are already vegan-friendly. When it comes to the shank bone, she said, she uses a beet – “as permitted in the Talmud, so no Jewish guilt here.” She is referencing the Pesachim tractate, page 114b, which quotes a sage noting that the two cooked items on the Passover table can be a beet and rice.In place of the egg, Leifer suggests using a colorful, plastic Easter egg. She then veganizes the rest of the meal – with vegetable matza ball soup; chopped “liver” made from mushrooms; and gefilte “fish” made out of potatoes, eggplant and onions.Passover isn’t the only holiday PETA is hoping to veganize. The organization also posted a video offering a recipe for vegan cream-filled chocolate eggs for Easter.
