Chick-fil-A is jumping on the plant-based bandwagon.

The Atlanta chain said Thursday that it's testing its first plant-based entrée, a breaded cauliflower sandwich, at restaurants in Denver; Charleston, South Carolina; and the Greensboro, North Carolina, area. The test begins Feb. 13.

Chick-fil-A said its culinary team spent four years developing the sandwich after guests told the chain they wanted to add more vegetables to their diets.

Chick-fil-A tested mushrooms, chickpeas and chopped vegetables formed into patties but kept returning to cauliflower for its mild flavor.

Like Chick-fil-A's signature chicken sandwich, the cauliflower steak is marinated, breaded, pressure-cooked and then served on a bun with two pickle slices.

Chick-fil-A is a relative latecomer to the plant-based fast food scene. Burger King started selling its Impossible Whopper — featuring a plant-based burger made by Impossible Foods — in 2019. Starbucks launched an Impossible sausage sandwich in 2020. McDonald's debuted its McPlant burger — developed with Beyond Meat — in the United Kingdom in 2021. And KFC began selling Beyond Meat nuggets last year.
