D.C. may have found its newest food critic.

Noah Koch, the 9-year-old winner of the White House’s Let’s Move! national nutritious food contest, wowed congressional staffers today at the second Healthy on the Hill event, aimed at promoting a healthy, plant-based diet.

Koch, who won the contest with his Vegan Powerhouse Pesto Pasta recipe, even explained what was wrong with the picture posted alongside his recipe.

“The picture is incorrect,” Koch told more than 120 staffers gathered in Rayburn. “First of all, the pesto was supposed to be very thick, and as you see on the picture there is very little pesto. The spinach is supposed to be cut up by blender, which you see is whole, and then there’s Parmesan cheese sprinkled on top, which I do not like and which does not fit vegan. And then the tomatoes are not supposed to be cut up; they’re supposed to be little cherry tomatoes.”

Koch also told the audience about his healthy lifestyle, and how he has never eaten his school’s cafeteria food.

“I run 5ks,” Koch said. “My family … they eat healthy just like me, but my friends in school aren’t as healthy and as physical as me.”

The Maine resident, who has cooked with his parents since he was 2, won a trip to the White House for his recipe and met President Barack Obama and first lady Michelle Obama at the White House Kids’ State Dinner on Tuesday.
