It's the 25th year that La Casa Garcia Restaurant and the We Give Thanks Foundation have been providing a free meal to the needy.
An estimated 20,000 people were expected to show up at the Honda Center for the event, which runs from 11 a.m. to 3 p.m.
"[My children] don't have a place where we can celebrate. It's kind of sad to see them home and them knowing that everybody's together as a family and we don't have a family to share this day. So it's a good place to be here," said Erika Martinez of Buena Park.
The preparation started days ago. There's expected to be 700 turkeys, 100 pounds of gravy, 6,500 pounds of vegetables and 5,000 pies.
"Anybody is welcome. You come and eat with me, you're my family. I don't care where you come from," said Frank Garcia, owner of La Casa Garcia Restaurant.
Anaheim Ducks players were expected to be among the 2,000 volunteers serving up the traditional Thanksgiving meals.
