It's the Feastocrat's job to organise food for the event. They will usually arrange for a group of people, a feasting team, to be involved in the preparations and cooking both before the feast and on the day, and delegate different tasks or dishes to be made to each person, organise kitchen space, a clean-up crew etc. They are frequently involved in redacting recipes.
They are responsible for: the estimated food budget, doing the shopping, and obtaining any utensils necessary. Delegation is your friend. Everyone working with food must abide with all health and safety regulations.
