The latest burger to get on your list is a one-month-only collaboration between Haché and top cookbook author Sabrina Ghayour, giving things a little Middle-Eastern touch. She's created the Merguez Mama - and that's Haché’s 6oz prime hachéd steak burger topped with Merguez sausage, harissa ketchup, dill mayonnaise and crumbled feta, served in Haché’s signature brioche bun.
Launched and part of London Food Month, it's all for Action Against Hunger which will get £1 from every sale of the burger. Look out for it in all Hachés (Clapham, Chelsea, Camden, Shoreditch, Balham and Holborn) for the whole of June.
