$200 budget. Morning and Afternoon snack for 50 adults

It's teacher appreciation week at my son's daycare, and I'm responsible for buying snacks for one day for all the teachers/staff members (everyone contributed the money, it's just me taking that money and buying the stuff).

One snack will be set out during the morning break time and one in the afternoon break time. I can't really do things which require refrigeration or heat since the teachers have to rotate their breaks, so they'll be sitting out a while (otherwise I could buy like 75 hot dogs for afternoon snack).

If you were responsible for this, what would you get? Anything really fun that you think would be nice?
