Combining succulent rotisserie-style chicken, cool original Doritos, double mozzarella and cheddar, finished with the new creamy and tangy Buttermilk Ranch Sauce – a standout summer flavour. Decked in double denim – and a double holster stocked with Buttermilk Ranch – the 'Ranch Ranger', show jumper Fabian Williams, trotted through the city to hand-deliver Subway’s newest menu additions in a photo-worthy moment stopping Londononers in their tracks. Buttermilk Ranch is available now across participating Subway restaurants in the UK.
