Fry the minced meat (sauté with 2 tablespoons of oil), onion, clove of garlic, chilli pepper (s), add tomato (s), water and tomato paste. Season to taste and let it boil down a little.
In addition, of course, spaghetti!
TIP:
Cooking (albeit a little unusual) in the wok pan, because that`s where the minced meat is so easy to move aside.
