Linda McCartney Mozzarella Vegetarian Burgers £1.25
£1.25Get from Iceland
I absolutely love these Linda McCartney's 2 Vegetarian Mozzarella 1/4 LB Burgers and this is currently the best price on these that I can find, beating the likes of Tesco and Sainsbury's on the price.
PS. I normally pay £2 for them.
