Shake Shack Finally Launches a Vegetable-Based Veggie Burger Nationwide | Eater

"After largely resisting plant-based meat substitutes, the chain is rolling out a true-vegetable burger called the Veggie Shack that combines mushrooms, sweet potatoes, carrots, farro and quinoa; it had previously tested variations of this concept in select locations and until now relied mainly on a fried, cheese-filled 'Shroom Burger as its primary vegetarian offering. The nationwide launch signals a return to well-flavored, recognizable vegetable-and-legume patties at scale, reflecting both consumer interest in alternatives to lab-made “tech” burgers and the belief that thoughtfully seasoned real-vegetable options can satisfy a broad audience." - Bettina Makalintal
