So my office has cancelled the holiday party and instead we're having a potluck luncheon. Somehow, even I'm way low on the totem pole pay-wise, I'm stuck doing a main course, which I can't really afford to do for 19 people. Does anyone have any ideas on some sort of good hearty dish I can do relatively cheaply? Someone is already doing chili, rice, and there are a ton of desserts already signed up for. Thanks.
