The first family on Monday honored the legacy of Martin Luther King Jr. by spending the day participating in a service project at the DC Central Kitchen.

The kitchen, which was also celebrating its 25th anniversary on Monday, provides food for a variety of community programs while also teaching basic job skills to its workers.

Joining the Obamas was senior advisor Valerie Jarrett, who helped the family prepare meals for distribution to shelters around the area.

Many members of the Obama administration undertook similar ventures on the holiday.
