Start by either hand chopping or using a chopper to chop the onion, peppers and garlic. Then either using your hands, muslin/cheese cloth or a strainer remove all the water from the vegetables and add them to the meat.
Season the mixture with salt, paprika, urfa pepper, sumac and oregano. Then run it through the food processor for a pastier more melt in the mouth kebab or leave as is after mixing for a more meaty kebab texture.
Leave in the fridge to get cold. Once cool then skewer the meat and cook.
Best to pan fry using some oil on a grill pan. Alternatively if you can cook over a barbecue or coals then do that, baste with some butter while cooking if you are.
Serve with the salad once cooked. They don't take very long to cook, the meat will be nice and firm that will indicate that it's cooked.
