What are the most common approaches to doing the food?
Most courses provide a full meal for students. In some cases students prepare their own food and in some cases the food is prepared by others and brought to the venue. Many course administrators have contacted local churches running Alpha and ask if they would be willing to furnish a meal. Many have agreed to support a campus course in that way. Some courses offer dessert. This is especially true if a university requires students to participate in a meal plan.
