We're having a big Christmas party potluck on the 23rd, and it will be about 100 people there. I'm thinking cupcakes or truffles, but I'd like to do something with some substance to it. I'd like to do maybe a sandwich or pizza(s), or even something like chickpea fritters. Does anyone else have any ideas. There isn't an electrical outlet, so no crockpot (I have no way of transporting it anyway).
