New York (CNN Business) Arby's is turning the plant-based meat craze on its head by testing meat-based plants.

The new marketing scheme highlights Arby's meat-only credentials, reenforcing its slogan: "We have the meats."

McDonald's MCD The company says it has produced a new meat-vegetable hybrid food category called "megetables." It's an obvious troll against its fast food rivals, including Burger King and a dozen or so others, which are adding plant-based meat alternatives to their menus.

Arby's "marrots"

Arby's has no immediate plans to sell its crazy new concoctions in stores, and the blog post announcing the megetables reads fully tongue-in cheek. But an Arby's spokesman said the concept is "not a joke at all."

First from the Arby's test kitchen is the "Marrot," a meat-carrot made of turkey breast sliced into the shape of a carrot. It's then sous vide for an hour and rubbed down in a "special carrot marinade" made of dried carrot juice powder. It's then topped with a maple syrup powder, oven-roasted for an hour and topped with a parsley to "give it the full carrot effect," Arby's said.
