Are you a kid who's good at preparing healthful meals? Would you like to dine with First Lady Michelle Obama? If you answered yes to both questions, you should enter the Healthy Lunchtime Challenge.The contest invites kids ages 8 to 12 from across the country to come up with lunch recipes that are nutritious and delicious. More than 50 winners, including one from each state, will get to go to Washington, D.C., to attend a kids' State Dinner at the White House. The winning recipes will be served.

"We all want to ensure that our kids are eating nutritious, delicious food at every meal," Obama said. "With parents and kids all across the country getting creative in the kitchen, I know we'll find healthy meals that every family will enjoy."

A panel of expert judges, including assistant White House chef Sam Kass, will choose the winning recipes. The judges will be on the lookout for lunches that are healthful, tasty and affordable.

A winning lunch meal should have items from each of the food groups, including fruit, veggies, whole grains, protein and low-fat dairy foods. You could choose to combine them into one recipe or to create a meal that includes a main dish and side dishes. For more tips on preparing healthful meals, visit www.choosemyplate.gov.
