Firstly select someone to be a Chef. Group everyone else into groups of two. Each pair should choose a vegetable, but make sure no two pairs choose the same vegetable.
Then have everyone sit (on chairs) in a circle. People are not allowed to sit next to their pair. The Chef should stand in the middle of the circle.
The Chef then calls out the name of a vegetable. At their calling, the two people who are that vegetable need to quickly try and change seats, and the Chef needs to try and grab one of their spots whilst they are changing. If they do, they become that vegetable and the person who missed out becomes the Chef.
The Chef can also call out "Chef Salad" and everyone must change seats.
