IF we have guests for any holiday, we invite them to join us for that holiday dinner, letting the understand it is an invitation, not a command performance. One Easter we had a gentleman who was working in the area on night shift arrive at 4 AM (I left the door so he just had to push it to get in) and when he took the room I told him he was welcome to join us for Easter Dinner at 1 PM. He did and remarked how nice it was that we had invited him.
Anything edible is always nice, big enough to look like a nice gift but not so big as to feel obligated to give a gift in return. When we were in Illinois, I ordered 72 one pound jars of honey from West Virginia for several years to give to the co-workers are both of my jobs. That filled the bill perfectly. (A couple of the maintenance guys at my full-time used to ask me if I was getting the honey again. It was cute the way they would ask.)
