Hold onto your roast beef —vegetarians get their due on Feb. 29 when Arby's introduces a one-day-only vegetarian menu to each of its 3,400 outlets nationwide.

This comes from the restaurant behind the term "Meatcraft."

The menu, which is in honor of leap year, is comprised of items on the fast-food chain's standard menu, sans meat. The prices for the sandwiches will not change. And don't worry: Meat-filled sandwiches remain on the bill of fare.

"We’re proud of our meats and haven’t been shy about promoting them, so we wanted to show vegetarians that with a little creativity, Arby’s can fit into their diet as well," Arby's told Mashable.

Diners will be able to choose from options like the Reuben Sandwich, the Smokehouse Brisket Sandwich and the Beef 'n' Cheddar classic sandwich that are all lacking their eponymous ingredient. Vegetables, condiments and cheese reign supreme as the featured sandwich-stuffers.

In a press release, Chief Marketing Officer and Brand President Rob Lynch said, “If it goes well, we’ll likely bring back the vegetarian menu on Feb. 29 each year.”

We know you're thinking: Wait, I can get those sandwiches sans meat any time of year just by ordering them that way.

You can also drink eggnog any time of year. You can whip up a batch of matzo brei in the middle of the winter. You certainly don't have to wait for Oct. 31 to gorge yourself on your kids' candy stash while they sleep — you are an adult now, you can buy your own candy, remember?

But you probably don't do those things. You savor those foods on their specific holidays because the hubbub and excitement surrounding the day and food is part of the joy.

That's exactly why ordering a vegetarian sandwich from a roast beef emporium on a day that only comes around once every four years makes so much sense.

That and the fact that you can finally take your carnivorous spouse on a lunch date that won't involve crying about how tofu is the devil.
