Add a little oil to a large frying pan and preheat it on medium heat for 2 minutes.
Add the beef mince and flatten it with the back of a spoon into an even layer. Let it cook undisturbed for a few minutes so it forms a golden crust.
Break it up with a spoon, then season with salt, pepper, paprika, cumin, and chilli powder. Stir and fry for another 3 minutes.
Add the tomato purée and water. Cook for 6–7 more minutes, stirring occasionally. Set aside.
