a member of the clean plate club
Someone who always makes a point of eating everything they are served in a meal. Sometimes hyphenated as "clean-plate club." Come on, kids, finish the food I gave you. Don't you want to be members of the clean plate club? Our national obsession with being members of the clean-plate club, along with ever-increasing portion sizes, has led to people eating far more than they require. I've always been a picky eater, so I'm rarely a member of the clean plate club.
