We do alot of lunches as Relay for Life fundraising events, and the employees really enjoy it. I am looking for more lunch ideas, because they are asking for more.
Here are the ones we've had so far, that work really well. We have a potato bar lunch, where employees sign up to bring either potatoes, or a potato topper, such as bacon, chili, broccoli cheese sauce, butter, etc. On the morning of the lunch, we put all the potatoes in a cooker to bake, and they are done by lunch time! We charge $5 a person for the lunch, and usually have a big turn out.
We also have a sloppy joe lunch, with a sign up sheet where you can sign up to bring a crock pots of sloppy joe meat, or chips, a desert, buns, a potato salad, etc. The employees love it! It gives them a chance to try out their new recipes, etc. Those who don't cook sign up to bring things like chips, ketchup, etc.
There are times we have meetings that bring in employees from other locations, and if I schedule the lunch around the same time, I get more of a turnout.
