Thirteen hundred children entered the "Healthy Lunchtime Challenge" but only one child from each of the 50 states, three territories and D.C. won a seat at Tuesday's kids state dinner.
They won for creating a healthy and affordable recipe.
On Tuesday, they sampled some of their top recipes at the white house with First Lady Michelle Obama.
"Become a leader," she says. "You guys are more than equipped to do it - you're already doing it. So keep working hard."
They also got to dance with the first lady and had a surprise visitor - President Barack Obama.
The president stopped by to praise the group for leading the country toward healthier living.
"Not only are you going to live a better life, but helping to create a stronger, healthier America," he said.
The group finished the day with a visit to the White House gardens.
