Preheat oven to 180C / 350F.
Combine the meat, egg, onion, and spices in a large bowl. Mix very well.
Transfer the meat mixture to a loaf tin or two and press down firmly.
Bake for 30 minutes until the top is golden brown.
Remove the meat loaf from the tin and place on a baking tray. Bake for another 30 minutes to get a nice caramelized surface.
Let the meat settle for 15-20 minutes before slicing.
Serve in pita bread with tzatziki sauce, diced onion, tomato, cucumber, and lettuce.
I edited original recipe to remove breadcrumbs replacing with egg.
