Everyone’s vegan out.

Pizza Hut is the latest fast food chain to cater to customers who abstain from eating all animal products, including dairy, eggs and honey, as well as the meat and seafood avoided by vegetarians.

The pizza maker is testing dairy-free Violife cheese atop its pies at five of its U.K. restaurants from Oct. 11 through Nov. 26, and customers starved for vegan pizza options are eating it up.

Competitor Domino’s rolled out its first vegan pizza in Israel four years ago using a soy-based cheese. Customers didn’t like the taste of that, however, so the brand upgraded to a vegan cheese by U.K. brand VBites at 55 of its Israeli locations last month.

Pizza Hut and Domino’s aren’t dishing vegan pies in the U.S. yet, however, and neither company responded to Moneyish requests for comment.

And that growing plant-based foodie population has spurred plenty of other brands to drop the eggs, dairy and honey from their products.

The century-old Queens-based Elmhurst Dairy was put out to pasture last year – but has reinvented itself as a producer of vegan nut milks.
