When Mitch visits Morrie, he wants to feel as though he is contributing something. Additionally, he remembers Morrie's fondness for good food. Mitch feels helpless to assist Morrie in many ways, so he brings food as a means of helping in even the smallest way.
On the first Tuesday he visits, Mitch visits a local supermarket before arriving at Morrie's. He picks up turkey, potato salad, macaroni salad, and bagels. Morrie insists that Mitch sit and share some of the food with him as they talk.
Before visiting the next Tuesday, Mitch stops by Bread and Circus; he thinks Morrie must like the food there, as he had noticed several of their bags around the house during the previous visit. He purchases vermicelli with vegetables, carrot soup, and baklava to take to Morrie's house.
On the third Tuesday, Mitch brings more "normal" food: pasta with corn, potato salad, and apple cobbler.
Mitch is met by Morrie's wife on the sixth visit. When he shows her the food that he has brought for the visit, she gently explains that Morrie can't eat most foods anymore. She opens the refrigerator and freezer to reveal the food that Mitch had previously brought, still untouched. At this point in the disease's progression, Morrie can only eat very soft foods and drink things through a straw.
When Mitch visits on the tenth Tuesday, he stops again at Bread and Circus; he is careful to purchase only the softest foods. Still, when Morrie is given his lunch, it is not the carrot soup or Greek pasta which Mitch had brought. Morrie is only able to drink supplements, for the most part.
Although he realizes that he and Morrie will never be able to share a meal again, Mitch continues to bring food; he realizes on the tenth Tuesday that this hope is "foolish." Mitch must therefore release the idea of finding comfort through sharing meals together.
