Sandwich magazine takes an iconic sandwich and uses it as a lens for cultural essays, features, photo stories and more.

Here it is, our Christmas special – the Leftovers Sandwich issue... and it’s as packed as the muffaletto-style sandwich created for us by cover star, chef and food writer, Gizzi Erskine.

Alongside Gizzi, we have (deep breath) an inspirational chat with The Bronx’s magnificent food world disruptors, Ghetto Gastro; multi-award winning musical gourmand Benny Blanco gives us a playlist to dance off the calories; the mighty Michelin-starred Tom Kerridge picks a football team using only leftover ingredients in Leftover Rovers; Britain's Best Baker David Wright takes us through the history of mayonnaise; one of the world's foremost economic minds, Professor Ha-Joon Chang explains why the leftovers sandwich should be compared to Singapore, economically speaking; and we've got sandwich recipes from iconic chefs, Matty Matheson, Ixta Belfrage, Gerald Sombright, Anna Jones and Max Halley.

On a sustainability theme, we also have a photo essay on the huge composting facility that your food waste goes to, we feature six people you should follow on social media to help you be more sustainable, and we explore how South Korea got it's food recycling numbers from 5% to 95% in two decades…
