Every month at work my department of about 25 people has a potluck. Because we're in a big corporate office, we're limited as to what we can bring in. It's a pain to drag a crock pot up here (though possible in dire situations) and you can't really microwave food for 25 people very easily.
Typically I bring some type of cookie or cupcake, but the lazy folks who don't look at the sign up sheet always grab some baked garbage from the grocery store at the last minute so we end up with more sweets than anything else.
I'm looking for suggestions and recipes for appetizer type items, or main dishes that can be served at room temperature.
