Mix all the spices, except the salt and pepper, and set aside.
Cut the meat into thin shavings or narrow strips.
Heat a little oil in a frying pan and fry the meat over a medium heat, seasoning with salt and pepper.
Sprinkle over the spice mix and continue frying until the meat is well browned.
Meanwhile, prepare the vegetables: halve the tomatoes, shred the lettuce and cut the onion into half rings. Cut the cucumber in half, scrape out the seeds if you like, and cut into slices.
Divide the lettuce between 4 plates and top with the kebab meat, tomatoes, cucumber, red onion and your favourite dressing.
