When I opened my German-inspired beer hall, Wursthall, I wanted to offer a vegan sandwich that would be just as satisfying and delicious as the sausages and meat-based sandwiches on our menu. The result was this sandwich, inspired by döner kebab, a Turkish sandwich popular throughout Germany. It's gone on to be one of our most popular menu items. Even meat-eaters order it regularly.
Technique tip: Sumac and Urfa biber are essential Turkish spices that can be found in a good spice shop or ordered online.
Swap option: You can replace the vegan ground meat with ground beef or lamb, if you prefer.
For the Turkish-ish patties:
Combine all patty ingredients in a medium bowl and knead until homogenous and sticky.
Divide into 4 even piles and form into patties roughly the same length and width as your buns.
For the sumac onions:
Combine all sumac onion ingredients in a medium bowl and toss to combine.
For the sandwiches:
Heat vegetable oil in a large skillet over medium-high heat until shimmering. Add patties and cook without disturbing until well-browned on first side, about 2 minutes. Flip and cook on second side until just cooked through, about 1 minute longer. Transfer to a paper towel-lined plate.
Spread mayonnaise on toasted buns, top and bottom. Layer bottom buns with pickles, sumac onions and arugula. Drizzle with olive oil. Place a patty on top of arugula, top with pickled peppers, close sandwiches and serve.
