Not entirely sure about the admin side of it (and I probably can't say even if I did), but the kitchen has volunteers that cook and then a vehicle that goes around to them to pick the food up. It then comes to a pre planned spot to set up tables, and then you just serve

You can also bring along vegies, noodles, a gas stove and a pressure cooker if you want to cook onsite if food runs low. Gas stove is pretty much needed anyway for drinks like coffee tea and hot chocolate
