Place a wok or a large pan on medium heat.
When the pan is hot, add the lamb mince. Cook it until brown, breaking it down into small pieces with a wooden spoon.
Add olive oil if needed and then sauté the onions until soft and translucent without browning them.
Stir in the garlic and then sauté for another minute, stirring continuously, without burning the garlic.
Add the tomato paste, red pepper paste, chili flakes, freshly ground black pepper, and another ½ teaspoon of salt.
Cook for a few minutes and then add water, bring it to a boil and cook for another couple of minutes.
Remove the pan from the heat and build your kebab dish.
