I'm going to be vending an event that should bring in a 1000 people. Only two food venders will be there. I have only vended once I normally do comps. I know caterers go by oz per person and pounds per item.I want to go buy aluminum pans. I know two smoke pork butts will fill up a full sheet aluminum pan how many sandwiches will that make an estimate? We will have baked beans, Cole slaw, and Mac salad. how much would each one feed in full or half aluminum pans. and was an 8 ounce cup be enough for the sides. thanks for any help
