I am Jewish, so I feel extra lucky to have received an invitation to my neighbor's popular Christmas party this year. Everyone's supposed to bring a dish. I am pretty sure there will be too many sweets, so I want to bring a wowza savory dish. The only stipulations are that it has to be vegetarian (eggs and dairy ok), and it has to have festive holiday colors--red, green, and white are great but I'll do anything beautiful. OK, Serious Eaters, help me enhance the holiday spirit in a magnificent way!
