KFC is joining the healthier food trend by testing vegetarian fried chicken.

Foodbeast reports that it would be the first vegetarian fried chicken offered by a big-name quick-service chain.

Louisville-based KFC will test the product in the United Kingdom, and Foodbeast says smaller restaurants there, such as Temple Seitan, are famous for their versions of plant-based fried chicken.

Few details about the product were available, but it will use KFC's secret blend of 11 herbs and spices.

KFC UK told Foodbeast that it is still working on the recipe and plans to test it with customers this year and launch the product next year.

KFC UK hopes to cut its calories per serving by 20 percent in the next seven years, according to the report. And it will introduce meals that are under 600 calories by 2020.

KFC, part of Louisville-based Yum Brands Inc. (NYSE: YUM) has no plans to introduce the product in the U.S.
