WASHINGTON (Reuters) - First Lady Michelle Obama hosted for her last time the Kids' 'State Dinner' at the White House, celebrating and promoting healthy eating across the US.

Some of the 56 winning chef's dishes were featured in this fifth annual Healthy Lunchtime Challenge. Young chefs across the United States participate in a challenge to have their recipes selected by judges from Mrs Michelle Obama's "Let's Move" initiative.

The dinner, which was held this year at lunch time, includes some of the flare pomp and circumstance of a traditional state dinner, including a "roll call" line and entertainment.
