“We don’t have the meat.” That could be Arby’s slogan next week when the fast food giant ditches its meat-heavy menu for a vegetarian-friendly lineup, at least for one day.

Arby’s will turn its menu upside down on Feb. 29 (Leap Day) by replacing all the meat in its sandwiches with veggies, cheese, and other meat-less components. The menu items will be the same cost as their meaty counterparts.

The company claims the meat switch-up is not a joke, but its promotional photos that include a simple bun in place of the traditional roast beef are clearly satirical.

The one-day-only menu change is being promoted as an olive branch to vegetarians, who have very few options, unless ordered specially, at the restaurants on a normal day.

“At Arby’s, we’re proud of our meats, but we also understand that meat isn’t for everyone,” Rob Lynch, Chief Marketing Officer and Brand President of Arby’s Restaurant Group, said in a statement. “So we’ve decided to give vegetarians a reason to visit Arby’s on Leap Day by offering a one-day menu designed specifically for them. If it goes well, we’ll likely bring back the vegetarian menu on Feb. 29 each year.”

While Lynch’s suggestion that the company will bring back the vegetarian menu each year on Feb. 29 is obviously a joke, he doesn’t specify if the company would actually consider using the menu again in 2020, the next leap year.

Arby’s regular protein-packed menu is available as usual, the company says.
