The chain, which describes itself as offering 'naturally fast food', reported that the percentage of vegan burger sales has jumped from 41.3 percent to 56.8 percent in 2020.

The outlet currently offers two plant-based burgers - its LOVe burger, featuring a meat-free patty along with dairy-free cheese, mayo and salad was the first launch.
That was followed by the new Chipotle & Avocado Burger, topped with chipotle mayo and smashed guacamole. This new option has smashed predicted sales by 57 percent.
'Vegan sales have taken off'
"Vegan and veggie dishes have always been on LEON's menus, but we're now starting to see the market catch up," Erica Molyneaux, head of food at LEON, said.
"Sales of our vegan burgers have really taken off, with more than half of our sales now in vegan and vegetarian dishes.
"It's always been important to offer food that tastes and does people good, and that includes our range of plant-based dishes – bold, full of flavour and that everyone can enjoy."
