A cafe has unveiled the world's first vegan sandwich - made with IRN BRU. The sarny is served on toasted sourdough with rocket, cheese and pickles. Its barbecue sauce is made from pulled jackfruit and mushrooms - roasted in Irn Bru. The sandwich also comes with side-salad, air-fried chips or mac and cheese. Glaswegians have been flocking to try the £6.50 sandwich at the Serenity Now Cafe.
