The chef is a gnome that resides in the Beach party during Thanksgiving. He gave players Cooked turkey when asked for food.
When asked why he's there, he says "Why, we're having a feast. I'm cooking while the kids have some fun with the gnomeball net." If spoken to with two turkeys in your inventory, your character would immediately ask the "Why are you here?" option, followed by ending the conversation with the "Cheers" option. There was no normal way to get more than two turkeys at a time.
