This is a stall in Ridley Road Market in Dalston, they make the fluffiest flatbread in front of you, then smear it with this mystery meat spicy paste, put it through their giant revolving oven, roll it up for you, and then you eat it. Some things almost scare me in how they can supersede the sum of their parts and blow my socks right off with only 2 components. This is one of those things. There's a vegetarian version as well but I haven’t tried it, I’m sure it’s fine.
