Do you have air conditioning in your storage space? If so, crank it up! Get the temperature as low as you can.
Then make sandwiches the day of - way ahead of the event- and put in coolers with ice. Make sure the ice is contained in plastic so it doesn't soak the food. Once you've made the sandwiches and cole slaw, put into a container together with a fork and napkin (like a boxed lunch), then take to the event and hand out the boxes.
Hope this helps! Gina
