The White Castle Southwest Veggie Slider is the QSR brand's latest addition to its permanent menu as a meat-free sandwich that's slated to offer customers a great meal or snack option this season.
The sandwich consists of a burger patty made with sweet potatoes, black beans, corn, red bell peppers, onions and carrots. The patty is then covered in a brown rice crust to achieve a satisfying bite with smooth and crisp textures for variety. The recipe is paired with a seasoning blend that features chipotle and sweet barbecue flavors, while a slice of jalapeño cheddar rounds out the taste profile of the spice-led sandwich.
Chief Marketing Officer Jamie Richardson spoke on the White Castle Southwest Veggie Slider saying, "Our Cravers have been pretty vocal about wanting an alternative to traditional meat Sliders that doesn’t compromise on flavor. That prompted our menu innovation team to prioritize finding a craveable alternative, and we believe the Southwest Veggie Slider delivers on that in a big way."
