The first lady is asking children ages 8 to 12 and their parents to create nutritious lunch recipes that represent each of the food groups for "The Healthy Lunchtime Challenge."
Winners will travel to Washington to sample some of the original dishes at the second White House kids' "state dinner" luncheon this summer.
The deadline to submit recipes is May 12. Last year's challenge received more than 1,200 entries.
The contest, created by Epicurious.com, is a partnership among the food website, Mrs. Obama and the departments of Education and Agriculture.
