"There's a magical thing that happens out here on this day. It's just a day of caring, of sharing, of giving," said Ed Lough, volunteer coordinator.
Last year, nearly 300 event volunteers catered to the needs of the estimated 1,400 people who attended the feast, Lough said.
Volunteers also delivered meals to some 400 people who were unable to leave their homes.
Volunteers and hotel chefs this year will cook between 40 and 50 turkeys and hams, about 800 pounds of potatoes and massive vats of gravy and soup. They will prepare such trimmings as stuffing, vegetables, salads and desserts, Giannaris said.
Food manufacturers have donated items such as meat, bread and milk for the feast. Local businesses have also given food and some of the toys that the gathering's young guests receive after the meal, Giannaris said.
"I couldn't do this alone," he said. "It's not only Nick; there are so many people involved in this thing."
Lough, Walkley and George Turner, owner of Turner Transportation, are among the many volunteers who make the dinner a success each year, Giannaris said.
Volunteers "help us one year and they always come back," Turner said.

The look on children's faces when they open their gifts makes the effort that goes into holding the event worthwhile, Lough said.
"The sparkle in their eyes is worth their weight in gold," he said.
