A lunchroom mainstay is being recalled.

FOX's Lilian Woo reports:  

Nearly a thousand pounds of Lunchables being recalled by Kraft Heinz because of mislabeling and undeclared allergens on the label.

The affected variety, the Lunchables ham and American cracker stackers, which contain wheat and soy, not declared on the label. This according to the Department of Agriculture's Food Safety and Inspection Service.

They're mostly sold in Utah and California. The recalled 3.4-ounce boxes were manufactured on September 21 of this year and have a "use by" date of December 25. The company hasn't received any reports of illnesses.
