Fast-food chain White Castle recently announced the debut of a second vegan option, The Black Bean Slider. “Made with delicious black beans, red peppers and corn, the new Dr. Praeger’s patty is served on the signature White Castle slider bun,” White Castle wrote in its announcement of the new vegan slider. The chain removed l-cysteine—an additive derived most commonly from duck feathers—from its buns in 2015, effectively veganizing its veggie slider (that also features a Dr. Praeger’s patty). The chain also added a meat-centric slider but White Castle’s vice president Jamie Richardson is focused on promoting the new cruelty-free option. “Don’t miss out on these bold new sliders, especially a [vegan] option that’s Craver-tarian approved,” Richardson said. “Heck, it’s everyone approved.” The new slider can be enjoyed with White Castle’s (vegan) sweet Thai sauce for a limited time at most locations until June 1.
