Get the group into a circle. Then start out by saying your name and a food that begins with the same letter.
Then the next person does theirs, plus yours. Then the third person does theirs, the second’s and the first’s name and food.
It then moves on down the line, so that the last person has to do everyone with in the group.
Different variations of this can be played but it is great for getting the group to know one another and the names.
